Your round pool has a volume of 2463 cubic ft. The formula to achieve this is Pi * (radius squared) * depth of 4 ft. Converting this to U.S. Gallons comes to 18,425 gallons.
To calculate the number of gallons, first calculate the volume of the pool in cubic feet. The formula for the volume of a cylinder is pi * r^2 * h, where r is the radius and h is the height. In this case, the radius is 28 feet / 2 = 14 feet and the height is 48 inches / 12 = 4 feet. So the volume of the pool is pi * 14^2 * 4 cubic feet. Then, convert the volume to gallons by multiplying by the conversion factor of 7.48 gallons per cubic foot.
Assuming that 24' is the diameter of the pool, then the volume of the pool is 3,387,491.39 cubic inches. There are 231 cubic inches in a gallon, so the pool holds 14,664.46 gallons of water.
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.
6015.77 gallons
319.2 gallons for every inch the water in it is deep.
A round pool that is 16 feet across and is filled with 48 inches of water will contain about 6,041 gallons of water.

An 18x54 above ground round pool typically holds around 7,646 gallons of water when filled to the recommended level.
How large is the pool? In ground or above ground? Shape? Above ground is easier to calculate. I have an oval above ground pool which is 18 x 38. It holds approx. 15,000 gallons. To get an accurate answer, you need to be far more specific.

1 ft.3 (cubic) of water = 7.48 gallons How high is the pool? Is it 24 foot wide, 54 foot long and how deep? diameter x diameter x average depth x 5.9 = total gallons Allowing for the overflow/filter access, fill to 48" deep and use 13,000 gallons in a flat-bottomed pool.
