Question

A can of soup, shaped like a cylinder, has a diameter of 5 inches and a height of 8 inches. If 2 of these cans of soup are stacked on top of one another, about how large is the total surface area of the new cylinder that is formed?

Answer 1

I will assume that the can is with the top and bottom, the surface area is:
For 1 can,
A = 2πr(r + h).
A = 2π(2.5)(2.5+8)
A = 164.96

For 2 cans,
A=329.91
