The circumference of an 18-foot circular swimming pool is: 56.55 feet.
An 18' Round 52" wall above ground pool holds approximately 7300 gallons
This formula for swimming pool water capacity or volume is Length X Width X Average Depth X 28.32 (for liters in a cubic foot.) The equation for this pool is 18 X 33 X 4 X 28.32 Equals 67,288.32 liters in the swimming pool.
