<u>The surface area of the cylinder= 2 π * r^2</u>
<u>Step-by-step explanation</u>:
The surface area of each end and the surface area of the side of the cylinder are added to get surface area of a cylinder.
We know that each end of the cylinder is a circle.
So the surface area of each end of the cylinder is π * r^2
Here, r is the radius of the end
There are two ends, so their combined surface area= 2 π * r^2
<em><u>The surface area of the cylinder= 2 π * r^2</u></em>
