A can of soup is 3 inches in diameter and 5 inches in height. How much paper is needed to make a label for the soup can?

A label covers the curved side of the can, so its area is the can’s circumference times its height. The circumference is π × 3 inches, giving an area of π × 3 × 5 = 15π ≈ 47 square inches. The correct choice is 47 square inches.
