Surface Area Of A Cylinder

Surface Area Of A Cylinder Definition...

The number of square units it takes to exactly cover the surface of a cylinder.

How To Use This Formula..

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 * r2, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r2. 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. {{ http://www.aaamath.com/exp79x10.htm }}
