Question

Brittany is going to cover the label on a Pringle’s can and decorate it for Easter. The can has a diameter of 4.5 inches and a height of 14 inches. She only needs to cover the label, not the top or bottom of the can what is the minimum amount of paper needed?

Answer 1

Answer:

$197.92in^{2}$ or $198in^{2}$

Step-by-step explanation:

Since Brittany does need to to cover the top and bottom, we can use the formula $2\pi rh$

Let's first break down all the values that we already know.

h = 14 inches

diameter = 4.5

r = diameter / 2 = 2.25

Now that we broke down all our values, we then proceed to substitute all our values in the formula.

$2\pi rh$

$2\pi (2.25)(14)$

$2\pi (2.25)(14)$

$6.28(2.25)(14)$

$14.14(14)$

= $197.92in^{2}$ or $198in^{2}$
