Volume of a circular right cylinder is calculated by multiplying the base by the height. Since the base of a circular right cylinder is a circle then we have to calculate the area of the circle first then multiply it by the height of the cylinder.

V = B × h

Where *V* is the volume of the circular right cylinder, *B* is the area of the circle that forms the base of the cylinder, and *h* is the height of the cylinder.

The formula then will be:

V = hπr^{2}

Example:

If *h = 9* and *r = 5*

Then *V = ?*

V = 9 × 3.14 × 25 = 706.5 cubic units
