To calculate the amount of water in an 18-foot round pool, you first need to determine the volume. The formula for the volume of a cylinder (pool) is V = πr²h, where r is the radius and h is the height (or depth) of the pool. The radius is half of the diameter, so for an 18-foot pool, the radius is 9 feet. If you assume a typical depth of 4 feet, the volume would be approximately 1,018 cubic feet. Since there are about 7.48 gallons in a cubic foot, this translates to roughly 7,617 gallons of water.
