A cylinder is a 3-dimensional geometric figure which consists of circular bases and these bases when connected together form the curved surface of the cylinder. If the line joining the centers of the two congruent circular bases is perpendicular to the radius of the circles, then the cylinder is known as the right circular cylinder. Volume of a right circular cylinder is the product of the area of the circular base and the height of the cylinder.

 Example 1: What is the volume of the cylinder whose radius of the base is 4.5m and the height is 6m.

Given radius of the cylinder, r = 4.5m

Height of the cylinder, h = 6m

Volume of the cylinder, V = π * r2 * h

Substituting the radius and the height in the above volume formula, we get

Volume, V = π * (4.5m) 2 * (6m) ==> π * 20.25m2 * 6m

Volume, V = 121.5π

Volume of the cylinder, V = 381.7m3
 
Example 2: What is the volume of the cylinder whose radius of the base is 2.4m and the height is 5m.

Given radius of the cylinder, r = 2.4m

Height of the cylinder, h = 5m

Volume of the cylinder, V = π * r2 * h

Substituting the radius and the height in the above volume formula, we get

Volume, V = π * (2.4m) 2 * (5m) ==> π * 5.76m2 * 5m

Volume, V = 28.8π

Volume of the cylinder, V = 90.5m3
