Question

Mary is wrapping a can of paint to gift 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 for covering the can? ___
(Let π = 3.14)

Answer 1

In this problem
d = 7 inches
r = 3.5 inches
h = 11 inches
Surface Area = 2(3.14)(3.5) + 2 $\times$ (3.14) $\times$ 3.5 $\times$ 11
Surface Area = 77 + 242
Surface Area = 319 square inches of wrapping paper
