Answer:

The pool can hold about 5755 US gallon of water

Explanation:

From the illustration of the pool, we see the pool to be in cylindrical shape with 5 feet deep and has a radius of 7 feet.

Volume of a the pool = volume of a cylinder

Recall that volume of cylinder = πr²h

In this case

r = 7, h = 5, π = 3.14

Therefore:

Volume = πr²h

= 3.14 x 7² x 5

= 3.14 x 49 x 5

= 769.3ft³

How much water the pool can hold is

Since: 1 cubic foot = 7.481 US gallon of water

769.3ft³ = 769.3 * 7.481 US gallon of water

769.3ft³ = 5755.13 US gallon of water

The pool can hold about 5755 US gallon of
