How Many Gallons Is an 18 X 52 Pool?

If you are considering installing a swimming pool in your backyard, you might be wondering how many gallons of water it will hold. One popular size for above-ground pools is 18 feet in diameter and 52 inches in depth. To determine the number of gallons, you will need to calculate the pool’s volume.

To find the volume of a pool, you can use the formula for the volume of a cylinder: V = πr²h, where V is the volume, π is a mathematical constant (approximately 3.14), r is the radius (half the diameter), and h is the height or depth of the pool. In this case, the radius would be 18 feet divided by 2, which equals 9 feet.

Now, let’s calculate the volume of the pool:

V = 3.14 x 9² x 52
V = 3.14 x 81 x 52
V ≈ 13,346 gallons

Therefore, an 18-foot by 52-inch pool can hold approximately 13,346 gallons of water.

Common Questions:

1. How accurate is this calculation?
The calculation provides an estimation and may vary slightly depending on factors such as the actual shape of the pool.

2. Can I convert this measurement to other units?
