Answer:
<h2>C. 71.2 in²</h2>
Step-by-step explanation:
We have the square in the base with side a = 4in and four triangles with base a = 4in and height h = 6.9in.
The formula of an area of a square:
A = a²
Substitute:
As = 4² = 16 in²
The formula of an area of a triangle:
A = (ah)/2
Substitute:
At = [(4)(6.9)]/2 = 27.6/2 = 13.8 in²
The Surface Area:
S.A. = As + 4At
Substitute:
S.A. = 16 + 4(13.8) = 16 + 55.2 = 71.2 in²
The percent is 12% because 36/300 divided by 100 as the denominator it's divided by 3 and 36 divided by 3 is 12.

Step-by-step explanation:
The radius of trampoline is 6.5 feet
Step-by-step explanation:
Area of circular trampoline = 132.2 ft²
Let,
r be the radius of trampoline.
We know that area of circle =
Therefore,
Putting value of
Dividing both sides by 3.14
Taking square root on both sides
Rounding to nearest tenth,
Radius of trampoline = 6.5 feet
The radius of trampoline is 6.5 feet
