The height of the cylinder is 6 inches.

We'll be analyzing the surface area of a round cylinder - in other words the amount of material needed to "make a can".

A cylinder (round can) has a circular base and a circular top with vertical sides in between. Letr be the radius of the top of the can and lethbe the height.The surface area of the cylinder,A, isA=2r^2+2rh

(it's two circles for the top and bottom plus a rolled up rectangle for the side).

r = radius Areas = 1 1- h = height Area = h(2xr) Circumference
