This pool makes a cylinder. The formula for the volume of a cylinder is: pi X radius2 X height. The radius is one half of the diameter so, in this case, radius = 9 feet (18/2). The height is the depth of the pool, in this case, 4 feet. So, the volume of this cylinder is:
3.14 (pi) X 92 X 4 = 1017.36 cubic feet
They want the answer in gallons. One cubic foot is equal to 7.48 US gallons. So, the volume in US gallons is:
1017.36 X 7.48 = 7,609.53 US gallons
