How do you get the volume of a cylinder using the circumference and height?

Base x Height.... The base of a cylinder is a circle. So you first find the area of the circle. pi times the radius squared. (for example, with a cylinder with a radius of 2in and a height of 3in, the area of the base would be about 2 x 2 x 3.14 = 12.56 Then you multiply the area of the base with the height. So going with our example, 12.56 x 3 = 37.68 inches. Think about it this way: The volume of a rectangular prism is length x width x height. The base of a rectangular prism is a rectangle , and to find the area of that is length x width. So it's the area of the base (which is length x width) x the height.
