Question

Helena is going to cover the label on a Pringle’s can and decorate it for Easter. The can has a diameter of 4.5 in. and a height of 14 in. 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

197.92 in^2 or 198 in^2

Explanation:

Helena needs to cover the top and bottom so do the formula 2
`\pi`
`rh`

we know:

height = 14 inches

diameter = 4.5 inches

radius = diameter / 2

radius = 4.5/2

radius = 2.25

Now plug the values into the formula.

2
`\pi`
`rh`

2
`\pi`(2.25) (14)

6.28 (2.25) (14)

14.14 (14)

= 197.92 in^2 ---> 198 in^2
