baherus [9]

Answer:

Volume of a cylinder.

Step-by-step explanation:

The given equation is :

$V=\pi r^2 h$

Where

r is the radius

h is the height

This equation is used to find the volume of a cylinder.

For example, a cylinder having radius of 7 units and height of 10 units, its volume will be :

$V=\dfrac{22}{7}\times 7^2\times 10\\\\V=1540\ \text{unit}^2$

So, the given equation is used to find the volume of a cylinder.
