Here are the formulas you'll need:

Surface area:

Volume:

r is the radius of the cylinder and h is its height.

So for example, let's say you had a cylinder that had a radius of 3 cm and a height of 6 cm. For surface area, you would calculate:

For volume, you would calculate:

Then you divide the surface area/volume, which here is simply 1.

One note is that the units for surface area would be
