v/π=r²h
v/πr²=h
Answer and Step-by-step explanation:
The area of a circle:
![A = \pi r^{2}](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20r%5E%7B2%7D)
d = 2r
Plug in the values.
5.
A = ![\pi 7^{2}](https://tex.z-dn.net/?f=%5Cpi%207%5E%7B2%7D)
A = 49![\pi](https://tex.z-dn.net/?f=%5Cpi)
7.
58 = 2r
r = 29
![A = \pi 29^{2}](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%2029%5E%7B2%7D)
A = ![841\pi](https://tex.z-dn.net/?f=841%5Cpi)

The height of the fence is irrelevant. The bottom of the ladder is 3+8 = 11 feet from the building. The window is 14ft above the ground:
sqrt(14^2+11^2) = length of your ladder.
