Answer:

1175 gallons (rounded)

Explanation:

The volume of a cylinder is given by the formula
V=\pi r^2h .

r is the radius, h is the height.


V=\pi (5)^2 (2)=\pi(25)(2)=50\pi\approx 157.08 cubic feet

Each cubic foot contains 7.48 gallons, so
V=157.08* 7.48=1175 gallons (rounded).

Just for fun, each cubic foot weighs 62.4 pounds, so the water in the pool weighs about 9801 pounds -- more than 4 tons!
