Find the area of the circle use 3.14 for pie d=6ft
Answer:
28.26 ft.²
Step-by-step explanation:
Mathematics: Explain/formula.
To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.
[tex]\pi r^2(3.14*radius*radius)[/tex]
[tex]\pi =pi[/tex]
Mathematics: Solve.
Here, the diameter is 6 ft.
To find the radius, divide the diameter by 2.
[tex]6/2=3[/tex]
[tex]radius=3[/tex]
Now, we can plug the numbers into the formula.
[tex]\pi 3^2(3.14*3*3)=28.26[/tex]
Mathematics: Conclude.
Therefore, the area of this circle is 28.26 ft.²
the area of the given circle will be 28.27 ft².
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
Given, a circle that has a diameter of 6 ft,
Since, Radius = diameter/2
Thus,
Radius = 6/ 2
Radius = 3ft
From the formula of the area of the circle:
Area = pi* radius *radius
In our case,
Area = pi * 3 * 3
Area = 28.274
Therefore, the area of the given circle will be 28.27 ft².

can someone please help me find the missing angles to each variable
Answer:
x=130°
y=50°
z=130°
Step-by-step explanation:
__________
Answer:
x = 130°
y = 50°
z = 130°
Step-by-step explanation:
From the diagram, you can see that the angle given, 50° is a vertical angle to y. This means they are equal, so y = 50°.
Next, angle x, and the given 50° angle are supplementary since they form a straight line. Because of this, you get that:
50° + x = 180°
- and -
x = 130°
You can see that angle z is a vertical angle to angle x, so they are equal, which gives you z = x = 130°. --> z = 130°

A plane can fly 1440 miles in the same time as it takes a car to go 400 miles. If the car travels 130 mph
slower than the plane, find the speed of the plane.
mph
PLEASE PLEASE HELP
Answer:
The speed will be "144 mph".
Step-by-step explanation:
Let the speed of the plane be "x mph".
then,
The car's speed be "x-130 mph".
According to the question,
⇒ [tex]\frac{1440}{x} =\frac{400}{x-130}[/tex]
By applying cross-multiplication, we get
⇒ [tex]1440(x-130)=400x[/tex]
⇒ [tex]1440x-187200=400x[/tex]
⇒ [tex]1440x-140x=187200[/tex]
⇒ [tex]1300x=187200[/tex]
⇒ [tex]x=\frac{187200}{1300}[/tex]
⇒ [tex]=144 \ mph[/tex]

Step-by-step explanation:
Equation 1:
Dived both sides by 0.75 to remove 3/4 from x.
(x-12)=16
Now, add 12 to both sides.
x=28
Equation 2:
Same here, divide both sides by 0.75.
y-12=16
Add 12 to both sides.
y=28

He performs an experiment. Damian randomly removes a chew from the bag, records the result, and returns the chew to the bag. Damian performs the experiment 48 times. The results are shown below: A strawberry chew was selected 16 times. A cherry chew was selected 10 times. A peach chew was selected 22 times. Based on these results, express the probability that the next chew Damian removes from the bag will be cherry or peach as a fraction in simplest form.
Answer: 2/3
Step-by-step explanation:
The probability that the next chew Damian removes from the bag will be cherry or peach as a fraction in simplest form is 55/576
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability for the strawberry chews:
P(strawberry chews) = 16/48
Probability for the cherry chews:
P(cherry chews) = 10/48
Probability for the peach chews:
P(peach chews) = 22/48
Now the probability of cherry or peach = P(cherry)×P(peach)
[tex]=\frac{10}{48} \times\frac{22}{48}[/tex]
= 220/2304
= 55/576
Thus, the probability that the next chew Damian removes from the bag will be cherry or peach as a fraction in simplest form is 55/576

Express the series using sigma notation. 1 + 4 + 16 + ... + 256.
a.

d.
Please select the best answer from the choices provided
A
B
C
D
Answer:
D
Step-by-step explanation:
By looking at the terms, we can notice that each term is 4 times the previous term. This means the series is geometric and we can rule out options A and B because of this. We can find the first terms of both options C and D to get:
first term c: 4
first term d: 1
The first term of our series is one, so that must mean D is the answer.
