A 20 foot round pool has a radius of 3.2 feet. So the pool has a volume of pi*r2*h = 101.86 cubic ft approx.

The radius of a circle is half the diameter, so in this case, the radius of a 24-foot diameter pool would be 12 feet. The formula to find the radius from the diameter is: radius = diameter / 2. Therefore, the radius of a 24-foot diameter pool is 12 feet.

21 foot what? Radius, diameter or circimference? Presumably 4 feet deep?
Circumference = Pi x d: 3.14 x 16 = 50.24 feet

To calculate the volume of water in an 18-foot round pool that is 4 feet deep, you can use the formula for the volume of a cylinder: V = πr²h, where r is the radius and h is the height. The radius (r) is half the diameter, so for an 18-foot pool, the radius is 9 feet. Plugging in the values, the volume is approximately 508.94 cubic feet. Since 1 cubic foot equals about 7.48 gallons, the pool holds roughly 3,800 gallons of water.
