In the example below, we are going to calculate the volume of a solid cylinder. In order to do this we need to multiply the value of pie, times the radius squared, times the height of the cylinder. As we can see in the drawing, the radius of the cylinder is 4 feet and the height of the cylinder is 9 feet. With all of this information available we can calculate the volume using the provided formula. That means multiplying the value of pie, which is 3.14, times four feet squared, times 9 feet and come to a volume of 452.16 cubic feet
