How to Calculate Area of a Cylinder Using V=πr2h Formula?
Cylinder
Three-dimensional shape having a circular base is known as cylinder.
Volume
The volume of the cylinder is equal to capacity of the volume.

In order to calculate the volume occupied by a cylinder, we calculate the space occupied by each and every disk, add them up.
Thus, the volume of the cylinder is equal to product of the area of base and height.
For any cylinder with base radius ‘r’, and height ‘h’, the volume will be base multiple of height.
·
Since the base looks alike circle
Therefore, the volume of cylinder= (area of base) × height of the cylinder
Volume of a Hollow Cylinder
In case of hollow cylinder, we measure both radius, one for inner circle and one for outer circle which formed by the base of hollow cylinder.
Example
Find the volume of a hollow cylinder having inner
radius = 6 cm, outer
radius = 8 cm and
height = 7 cm (use pi = 22/7)
