Here are the formulas you’ll need: Surface area: ##2rh

Here are the formulas you’ll need: Surface area: ##2rh+2r^2## Volume: ##r^2h## 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: ##2(3)(6)+2(3)^2## which will give you ##54##. For volume you would calculate: ##(3)^2(6)## which would give you ##54## as well. Then you divide the surface area/volume which here is simply 1. One note is that the units for surface area would be ##cm^2## whereas for volume they would be ##cm^3##. Helpful image:
