what is the diameter of a circle with area of 113.04 square cm. use 3.14?
pls fast
Answer:
diameter of a circle = 12cm
Step-by-step explanation:
Area of a circle = πr²
113.04 cm² = πr²
First, search for radius (r) :-
r = √(113.04/π)
r = 6 cm
As diameter is equals to 2×radius
The diameter of a circle = 2 × 6cm
Final answer = 12 cm
Answer:
d≈12cm
Step-by-step explanation:
Using the formulas
A=πr2
d=2r
Solving for d
d=2A
π=2·113.04
π≈11.99696cm

Answer:
1953125
Step-by-step explanation:
Answer:
1953125
Step-by-step explanation:
5*5 = 25
25*5 = 125
125*5 = 625
625*5 = 3125
3125*5 = 15625
15625*5 = 78125
78125*5 = 390625
390625*5 = 1953125
1953125*1 = 1953125 Answer

A trapezoid has a height of 8 cm and bases with lengths of 14 cm and 8 cm. Tina says the area of the trapezoid is 176 cm2.
Find her error, and correct the error.
Tina did not multiply by _ . The correct area is _ cm2.
Answer:
Step-by-step explanation:
Let's do this properly:
Area of trapezoid = average length times height.
Here,
Area = (1/2)(8 cm + 14 cm)(8 cm), or
= (11 cm)(8 cm) = 88 cm^2
It appears that Tina forgot to divide the sum of 14 cm and 8 cm by 2. Thus, her answer is twice as large as it should be.

Simplify the following expression.
12 -2(x + 1)
Write the equation of the line in slope-intercept form using y=mx+b
Answer:
y = 4x + 4
Step-by-step explanation:
Two points you can see on the graph are (0,4) and (-2,-4)
Now, to find the slope, use delta y/ delta x
(-4-4)/(-2-0)
(-8)/(-2) = 4
Slope is 4.
y = 4x + b
Now, to find b, we need the y-intercept, which is the point where x is 0 and the graph crosses the y-axis.
This value is 4. So, the y-intercept is 4
Substitute into your equation
y = 4x + 4

Find the surface area of the triangular prism.
Answer:
First picture: 60
Second picture:
Step-by-step explanation:
The first step for the first picture is to find the area of the triangle on top. In order to do that, we have to use the equation: (W*L*1/2)
(3*4*1/2)=6
Then, we multiply the above equation by the Height. Which makes the equation become 60.
The first step for the second picture is the same. We first find the area of the triangle on top.
(12*9*1/2)=54
Then we multiply the height by our above answer.
(54*20)=1,080
The other measurements that were there aren't needed. So, next time, completely ignore them!
Hope you have a good day/night! Good luck!

Hi i'd love to help! but what is this comprehension about?
In the figure given below, calculate x and y.
Answer:
x = 73°
y = 39°
Step-by-step explanation:
x + 107 = 180 {Linear pair}
x = 180 - 107 {Subtract 107 from both sides}
x = 73°
y + 51 + 90 = 180 {straight line angles}
y + 141 = 180
y = 180 - 141
y = 39°

plug 88 into h and solve for t
what is m = -8; (-2, 16) in slope intercept form? :)
Answer:
y = -8x
Step-by-step explanation:
First let's look at what slope-intercept form is.
y = mx + b
m is the slope, which in this case is -8.
b is the y-intercept, which we will find later.
Now that we have identified the parts of the equation, let's plug in what we know. Use the point given for your x and y values.
y = mx + b
16 = -8(-2) + b
Let's simplify this to find b.
[multiply] 16 = 16 + b
[subtract 16] 0 = b
We now have our b-value, which is also our y-intercept. Plug in this value into the standard slope-intercept equation.
y = -8x
This is your equation.
Check this by plugging in the point again.
16 = -8(-2)
[multiply] 16 = 16
This expression is true; therefore, your answer is correct.
Hope this helps!

Find the surface area of the triangular prism.
Answer:
Triangular prism 1: 132
Triangular prism 2: 828
Step-by-step explanation:
1) triangle+triangle+rectangle+rectangle+rectangle
A of triangle=3*4 divided by 2
12/2= 6
since there are 2 triangles we do 6*2= 12
A of rectangle 1= 10*5= 50
A of rectangle 2= 10*4= 40
A of rectangle 3= 10*3= 30
so SA of whole figure is 12+50+40+30= 132
2) triangle+triangle+rectangle+rectangle+rectangle
A of triangle=9*12 divided by 2
108/2=54
since there are 2 triangles we do 54*2=108
A of rectangle 1= 9*20=180
A of rectangle 2= 15*20=300
A of rectangle 3= 12*20= 240
so SA of whole figure is 108+180+300+240=828

Write the equation of the line in slope-intercept form using y=mx+b
Answer:
y = 3/1x + 5
Step-by-step explanation:
The line crosses the y-axis at 5, meaning the y intercept is 5.
The slope has a rise of 3 and run of 1, making the slope 3/1.
