You could have looked this up as easily as posting it. Cubic feet = L x W x H = 4800 cubic feet of water. One cubic foot = 7.48052 gallons. Therefore 4800 x 7.48052 = 35906.496 gallons

There are 13,536 gallons in a 24 foot diameter pool that has 4 feet of water. Not true for a pool that is 4 feet in height. This would hold less than 4 feet of water.

pie times 12 squared time 5 divided by 0.133680556 cubic feet per gallon Answer is 53,283 Gallons

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.

21 foot what? Radius, diameter or circimference? Presumably 4 feet deep?

You don't say how deep the pool is and whether you're using US or UK gallons. However... One cubic foot contains approximately 7.5 US gallons, or 6.25 UK gallons, so if you multiply 10 x 3 x (pool depth) by either of the above you will get the approximate gallon count.
