Step-by-step explanation:

The cylinder is a closed figure which consists of two circular ends. If r is the radius and h is the height of the cylinder, then its surface area is given by :

or

We also know that, surface area = perimeter×height

So, the surface area of the cylinder is the product of circumference of the circle and height of the cylinder.
