ANSWER: about 126 in²

SHOW WORK:


1. A cylindrical container's lateral surface is to be covered by a label. If the container's diameter is 5 inches and its height is 8 inches, how much paper is needed to create the label?

lateral surface area = 2πrh

If d = 5, then r = 2.5 and h = 8, so lateral surface area = 2π(2.5)(8) = 40π ≈ 125.66
