ReteachVolume of Cylinders309372055499000As with prisms, the area of the base of a cylinder tells the number of cubic units in one layer. The height tells how many layers there are in the cylinder. The volume V of a cylinder with radius r is the area of the base B times the height h.V = Bh, where B = πr2, or V = πr2h437197514795500ExampleFind the volume of the cylinder.
