# How Many Gallons Is an 18×52 Pool

How Many Gallons Is an 18×52 Pool?

When it comes to determining the number of gallons in a swimming pool, it is essential to consider its dimensions. One common pool size is 18×52, which refers to a pool that is 18 feet in diameter and 52 inches deep. To calculate the number of gallons in this pool, you need to know the formula for finding the volume of a cylinder.

The formula for calculating the volume of a cylinder is V = πr²h, where V represents the volume, π is a mathematical constant approximately equal to 3.14, r is the radius of the pool, and h is the height or depth of the pool.

To find the radius of an 18-foot pool, you need to divide the diameter by 2. So, the radius of an 18-foot pool is 9 feet (18/2 = 9). Thus, the formula for finding the volume of an 18×52 pool becomes V = 3.14 x 9² x 52.

Now, let’s calculate the volume:

V = 3.14 x 81 x 52
V = 13339.68 cubic feet

To convert cubic feet to gallons, you need to know that 1 cubic foot is approximately equal to 7.48 gallons. Therefore, the number of gallons in an 18×52 pool is:

13339.68 x 7.48 = 99710.46 gallons

So, an 18×52 pool has a capacity of approximately 99,710 gallons.
