How many gallons of water in a pool 15 feet round and 33 inches deep?

Answer 1

Between 41 and 42. You need to find the volume, then multiply by the number of gallons in a cubic foot. For the volume of a round pool, you need the radius and depth. You have the circumference (15) so divide that by pi (3.14) and that gives you the diameter. (4.77) Radius is half the diameter (2.38) Now that you have the radius, square that (multiply it times itself) then multiply THAT number by pi (3.14) You now have the area. Take the 33 inches and change it to feet (divide 33 by 12 inches) You should get 2.25 feet. Multiply the AREA you got by the depth, and that will tell you the volume in cubic feet. Now multiply the volume by 7.48 (number of gallons in a cubic foot) and that will be your answer.
