Mathematics

Area = 229.6125in^2

Step-by-step 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

$r = \frac{1}{2}d$

So, we have:

$r = \frac{1}{2} *4.5$

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
