That depends.

Do you want the lateral surface area or the total surface area?

The lateral surface area is the area of the side of the cylinder excluding the area of the circular base. It is found by multiplying the circumference of the base times the height of the height of the cylinder. Think of it this way: if you cut the ends off of a soup can and then unrolled the side of the can, you would have a rectangle that measures the height of the can by the circumference of the circular end of the can. Note that the circumference of a circle is in terms of the measure of the radius.

Hence, lateral surface area is given by:

Total surface area is the lateral surface area plus the area of the two circular bases. The area of one of the bases is
