The circumference of a circle divided by its diameter is the value of pi and pi has a wide range of uses some of which are:- Finding the volume of a sphere Finding the surface area of a sphere Finding the volume of a cone Finding the volume of a cylinder Finding the area of a circle Finding the circumference of a circle

volume of cylinder pir2h

The volume of a cylinder is the cross-sectional area of the cylinder multiplied by its length. The perpendicular cross-section of a cylinder is a circle.

The formula for volume of a cylinder is (pi *r2 )h

The volume of a cylinder is calculated by using this formula:radius2 x Pi x length
