The rectangular label will completely cover the lateral surface of the can using as little paper as possible. If the can has a height of 8 cm and a diameter of 7 cm, then what are the width and length (to the nearest centimeter) of the label?

Answer 1

The length of the label will be he circumference of the can.
The width of the label will be the height of the can.

Answer 2

Width of label=height of can=8 cm
Length of label=circumference of can=2*pi*radius or pi*diameter.
Circumference=7*pi, this is the length of the label also.
