Question

Find the surface area of the cylinder in terms of ​.

Answer 1

The surface area of the cylinder=  2 π * r^2

Step-by-step explanation:

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

The surface area of the cylinder=  2 π * r^2
