A round pool that is 16 feet across and is filled with 48 inches of water will contain about 6,041 gallons of water.

If 16 ft = diameter, and 4 ft = height V = pi x r2 x h = 803.84 cubic feet; 1 cubic foot = 7.5 gallons, so multiply by 7.5 = 6028.8 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.
I have a 12' above ground round pool that is fillable up to about 29 inches and it holds roughly about 1600 gallons so yours will probably hold more than 2000 gallons.
