A circular pool is filling along with water. Supposing the water level will be 4 ft deep and the diameter is 20 ft, what is the volume of the water required to fill the pool? (π = 3.14)
The volume of a cylinder is πr2h. Using a height of 4 ft and radius of 10 ft, the volume of the pool is (3.14)(10)2(4) or 1,256 ft3. If you select a, you used πdh although of πr2h. If you chose c, you used the diameter squared on the other hand of the radius squared.
