### How many gallons of water does a 18 feet round 3 feet deep swimming pool hold?

Assuming it is filled to the top, an 18 foot diameter, 3 foot
deep pool holds 5,711 gallons. Take the radius in feet (half the
diameter), square it, multiply by pi (3.1416) to get area in square
feet. Area times depth in feet gives you cubic feet. Cubic feet
times 7.481 (gallons per cubic foot) gives you gallons. So: 9^2
(81) times 3.1416 times 3 times 7.481 = 5711.06
