Question

Abigail is going to cover the label on a Pringle's can and decorate it for

Mother's Day. The can has a diameter of 4.5 inches and a height of 14
inches. What is the minimum amount of paper that she needs for the
project?

Answer 1

`Area = 229.6125in^2`

Explanation:

Given

`h = 14in` --- height

`d =4.5in` --- diameter

Required

The minimum amount of paper needed

This implies that we calculate the surface area of the can (cylinder)

This is calculated as:

`Area = 2\pi r(r + h)`

Where

`r = (1)/(2)d`

So, we have:

`r = (1)/(2) *4.5`

`r = 2.25`

This gives:

`Area = 2 * 3.14 * 2.25(2.25 + 14)`

`Area = 2 * 3.14 * 2.25*16.25`

`Area = 229.6125in^2`
