Quickly please!! A circular swimming pool has a diameter of 20 ft and a height of 5 feet. What is the volume of the pool when it has no water in it?
Such a pool assumes the shape of a cylinder. volume of a cylinder= pi * radius*radius*height = 3.14 * 10 *10*5 = 314 * 5 = 1570 feet^3 in short 1570 cubic feet is the answer.
