Although there are many uses for finding out the area of a cylinder (most having to do with school work) the only one I could think of was for finding out the displacement of a liquid.
So there are four (4) parts to finding out the surface area of a cylinder.
Surface area will now be known as the letter X. (Surface area = X)
The formula we will be using is 2(pi r 2) + (2 pi r)* h = X
Step 1: First step...
The first of the steps involves breaking down the parts of a cylinder.
You have both the top and the bottom of the cylinder and the side.
The top and the bottom would be 2 circles of the same size.
