How much water do a 15 ft round pool hold?

A 15-foot round pool holds approximately 4,700 gallons of water when filled to capacity. To calculate this, you can use the formula for the volume of a cylinder: Volume = π × radius² × height. For a typical above-ground pool with an average depth of about 4 feet, this results in roughly 4,700 gallons. Keep in mind that the actual volume may vary based on the exact dimensions and shape of the pool.
