Question

2. A water tank is in the shape of a right circular cylinder with a height of 9

feet and a volume of 225 pi cubic feet. What is the diameter of the water
tank? *

Answer 1

10 ft.

Explanation:

V = Bh where B = area of the base, which is a circle in your problem.

So, B =
`\pi r^(2)`

225π = π
`r^(2)`(9)

`r^(2)` = 25

r = 5 ft

diameter = 2r = 10 ft.
