Answer:
The perimeter of the stained glass semi-circle is 3π feet.
Step-by-step explanation:
The perimeter of a semi-circle is half of the circumference of the full circle with the same diameter.
The circumference of a circle with diameter 3 feet is:
C = πd = π(3) = 3π feet
Therefore, the circumference of the full circle is 3π feet, and the circumference of the semi-circle is half of that:
C(semi-circle) = 1/2(3π) = 3/2π feet
However, the stained glass semi-circle has a curved edge, so we need to add the length of that edge to the perimeter. The curved edge of a semi-circle is half of the circumference of the full circle, or:
C(curved edge) = 1/2(2πr) = πr, where r is the radius of the circle
Since the diameter of the circle is 3 feet, the radius is half of that:
r = d/2 = 3/2 feet
So the curved edge of the stained glass semi-circle is:
C(curved edge) = π(3/2) = 3/2π feet
Adding this to the straight edge perimeter, we get:
Perimeter = C(semi-circle) + C(curved edge)
= (3/2π) + (3/2π)
= 3π feet
Therefore, the perimeter of the stained glass semi-circle is 3π feet.

What is the perimeter of this composite shape? ___ ft.
Use 3.14 for "pi" and round to the nearest hundredths place
Answer:
36.85 ft
Step-by-step explanation:
3 feet on either end + 6 feet on either side + circumference of the circle
3 + 3 + 6 + 6 + circumference of the circle
18 + circumference of the circle
You can find the circle's diameter by subtracting 6 from 12. You get 6. You can find the radius by dividing the diameter by 2. You get 3.
The formula for circumference is 2·π·Radius
2 · π · 3 = 6 · π = 6 · 3.14 ≈ 36.85

A
35 feet
B
20 feet
C
30 feet
D
25 feet
Answer:
The answer is D!
Step-by-step explanation:
Firs you have to do 10 divided into 2, the answer is 5. Now you have to do 5 x 5 that will get you 25. So D is the answer! (25 feet)

A circular cookie cake is 113.04 square inches. What is the diameter of the cookie cake? Approximate using π = 3.14.
6 inches
12 inches
24 inches
36 inches
Answer:
6 inches
Step-by-step explanation:
a = [tex]\pi r^{2}[/tex]
113.04 = 3.14[tex]r^{2}[/tex] Divide both sides by 3.14
36 = [tex]r^{2}[/tex]
[tex]\sqrt{36}[/tex] = [tex]\sqrt{r^{2} }[/tex]
6 = r
Helping in the name of Jesus.
Answer:6 inches.
Step-by-step explanation: What is the radius of a circle with an area of 113.04 square inches?
Radius of the circle is of 3 inches.
Step-by-step explanation:
It is given that the area of the circle is 113.04,
Let the radius of the circle be of "a" units
=======================
From the properties of circle, we know : -
Area of circle = πr^2 , where r is the radius of the circle.
======================
Then, comparing the question with the identity :
= > πr^2 = 113.04 sq. inches
= > 3.14 x r^2 = 113.04 sq. inches
= > r^2 = 113.04 / 3.14 sq.inches
= > r^2 = 36 sq. inches
= > r = 6 inches
Hence,
r or radius of the circle is of 6 inches.

Answer: To use the calculator: Enter the corresponding values into the boxes below and ... to and add to. i) In a quadratic equation in the form ax2 bx c 0, if.
Step-by-step explanation:
According to the information, we can infer that some coordinates of this quadratic equation are: (-2, -3), (-1, -0.75), (0, 0), (1, -0.75), and (2, -3)
How to solve the quadratic equation?To solve the quadratic equation, we need to set the equation equal to zero:
-0.75x^2 = 0Now, we can divide both sides by -0.75 to isolate x^2:
x^2 = 0/(-0.75)x^2 = 0Taking the square root of both sides, we get:
x = 0Therefore, the solution to the quadratic equation s(x) = -0.75x^2 is x = 0.
According to the previous information, we can infer that the equation s(x) = -0.75x^2 represents a downward facing parabola. Here are 5 possible coordinates on this curve:

Box and Whisker Plot
box plot
Description
A Box and Whisker Plot (or Box Plot) is a convenient way of visually displaying the data distribution through their quartiles.
The lines extending parallel from the boxes are known as the “whiskers”, which are used to indicate variability outside the upper and lower quartiles. Outliers are sometimes plotted as individual dots that are in-line with whiskers. Box Plots can be drawn either vertically or horizontally.
Although Box Plots may seem primitive in comparison to a Histogram or Density Plot, they have the advantage of taking up less space, which is useful when comparing distributions between many groups or datasets.
Here are the types of observations one can make from viewing a Box Plot:
What the key values are, such as: the average, median, 25th percentile, etc.
If there are any outliers and what their values are.
If the data is symmetrical or not.
How tightly is the data grouped.
If the data is skewed and if so, in what direction.
Two of the most commonly used variation of Box Plot are: variable-width Box Plots and notched Box Plots.

What is the distance traveled by the tip of the second hand of a clock in 1 minute if the hand is 10.5 inches long? Leave your answer in terms of π.
Answer:
(1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.
Step-by-step explanation:
The distance travelled by the tip of the second hand of a clock in 1 minute, if the hand is 6 cm long, is approximately 3.6 degrees or approximately 0.06283185 radians. This is because the circumference of a complete circle is equal to 2π radians, and a clock face is divided into 60 equal parts, so each part is equal to 1/60 of 2π or 1/30π radians. To convert this to cm, you can multiply by the length of the second hand, which is 6 cm. Therefore, the distance travelled is (1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

Answer:
D. None of the above.
Step-by-step explanation:
To evaluate the expression when x = 6, we substitute 6 for x in the expression:
2 - 3(x - 5)
= 2 - 3(6 - 5)
= 2 - 3(1)
= 2 - 3
= -1
Therefore, the value of the expression when x = 6 is -1.
So, the answer is D. None of the above.
Answer: none of the above
Step-by-step explanation:
When x = 6 We substitute 6 for x in the expression:
2 - 3(x - 5)
2 - 3(6 - 5)
2 - 3(1)
2 - 3
= -1

The time needed for the rocket to be 30 feet of the ground is given as follows:
t = 9.6 seconds.
How to obtain the time needed?The quadratic function giving the rocket's height after t seconds is given as follows:
h(t) = -16t² + 150t + 70.
The rocket will be 30 feet of the ground when:
h(t) = 30.
Hence:
-16t² + 150t + 70 = 30
16t² - 150t - 40 = 0.
The coefficients of the quadratic function are given as follows:
a = 16, b = -150, c = -40.
Time is a positive measure, hence, using a quadratic function calculator, the positive root is given as follows:

PLEASE Show work and explain! Use proportion. Due in 12 hours.
Answer: 200/7
Step-by-step explanation:
This creates 3 similar right triangle
you would put similar parts on top and the similar parts on bottom of proportions.
ex.
[tex]\frac{hypotenuse}{short leg} = \frac{hypotenuse}{short leg}[/tex]
in your problem they gave the short legs and long legs of right triangel
The line that they share in middle of the triangle is the long leg for the triangle on right and it is also the short leg for triangle on left.
[tex]\frac{long leg}{short leg} =\frac{long leg}{short leg}[/tex]
[tex]\frac{x}{20} = \frac{20}{14}[/tex]
x=(400)/14 = 200/7
You could also make your proportion where
parts of 1 triangle = equivalent parts of the other
ex.
[tex]\frac{long leg from big triangle}{long leg from small triangle} = \frac{short leg big triangle}{short leg from small triangle}[/tex]
The length of a cell phone is 1.4 1.4 inches and the width is 4.2 4.2 inches. The company making the cell phone wants to make a new version whose length will be 1.75 1.75 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?
If the side lengths of the new phone are proportional to the old phone, then we can set up a proportion:
1.4/4.2 = 1.75/x
Solving for x, we get:
x = 5.25 inches
So the width of the new phone will be 5.25 inches.

Answer:
x = 19
Step-by-step explanation:
We can see that the angles (2x + 4) and (8x - 14) are supplementary — they add to 180. From this observation, we can form the equation that can be solved for x:
(2x + 4) + (8x - 14) = 180
↓ combining like terms
10x - 10 = 180
↓ adding 10 to both sides
10x = 190
↓ dividing both sides by 10
x = 19

V is for Volume.
s is for the measurement of the side.
3 is for the length, width, and height.
First, just plug the number in; V=3^3. Or 3×3×3.
Second, Multiply; V=27
