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.

Cut the left over tube to create a rectangle.

e.g. 2(pi r

^{2}) or 2 x (3.14 x Radius squared)^{Note: }Do the stuff inside the parentheses first.You get that little exponent thingie by using the enriched text mode btw.

Good instructable though. I'm a couple of years late on commenting but these things last forever, right?
