### Hey....what's that funny looking thing Ms. Ireland?

To find the surface area of a cylinder add the surface area of each end plus the surface area of the side. Each end is a circle so the surface area of each end is π * r

^{2}, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r^{2}. The surface area of the side is the circumference times the height or 2 π * r * h, where r is the radius and h is the height of the side. Whew! That is a lot of information.Here is the entire formula for the surface area of a cylinder is 2 π r

^{2}+ 2 π r h. Remember BEDMAS, evaluate exponents first, then multiply, then add. VOILA, your done.

The curved surface area (CSA) of acylinderwith radiusrand heighthis given byI think it is important that you can recognize the difference between the CSA and SA as well as the relationship that exists between both of them.
