# How many gallons does it take to fill a 24ft round by 4ft deep pool? ###### 2006-07-03 22:03:10

The volume of a right circular cylinder is computed by the equation: volume = pi * radius squared * height In your case: radius = 12 ft, squared it equals 144ft squared height = 4 ft pi = 3.14159........ This will get you volume in cubic feet, the conversion factor from cubic feet to gallons is: cubic foot * 7.4805 = gallon Put it all together: Volume = 3.14159 * 144 * 4 * 7.4805 and you get: 13,536.4 gallons Which is a lot of water.

## Related Questions I can calculate how much water it will take to fill the pool but not the cost. The cost has to be determined by how much you pay for water where you live. The volume of the 24ft round pool x 5ft deep pool (assuming the dimensions given are inside dimensions) is 2,261.952 cu ft and will hold 16,921.662 gallons of water.
