Question

Russell is filling a cylinder-shaped swimming pool that has a diameter of 20 feet. He fills it with water to a depth of 3 feet. What is the volume of the water in the pool, to the nearest cubic foot

Answer 1

Answer:
`V=942.6\ ft^3`

Explanation:

Given

Diameter of swimming pool is
`d=20\ ft\quad \quad (\text{radius}\ r=10\ ft)`

Russell fills it to a depth of
`h=3\ ft`

If the pool is in the shape of cylinder then its volume is given by

`V=\pi * r^2* h`

`V=\pi * (10)^2* 3`

`V=942.6\ ft^3`
