Answer:
The volume of the cylinder is 2002 square units.
Step-by-step explanation:
It is given that,
Height of the cylinder, h = 13 units
Radius of the cylinder, r = 7 units
We need to find the volume of the cylinder. The formula of the volume of cylinder is given by :

So, the volume of the cylinder is 2002 square units.
