Question

Jamie is wrapping a can of paint as a gag gift for a friend. If the can is 11 inches high and has a diameter of 7 inches, how many square inches of wrapping paper will she use in completely covering the can?

Answer 1

A can of paint is a cylinder, so we must use the surface area for a cylinder.
2($\pi$r$r^{2}$) is the top and bottom.

The surface of the can is a rectangle with a length equal to the circumference of the can.
