To find the amount of paper used for the label, you will find the area of the circular surface
going around the can.
If you unrolled it, it will be in the shape of a rectangle. The circumference of the circle represents the length, and the height of the can represents the width of the label.
A = lw
Length (pi x d) x width(height of the can)
(3.14 x 4 inches) x 3 inches = 37.68 in.².
The area of the label is 37.68 in.².
