There are 16 cans of soup in a carton. Each can has a diameter of 8 cm and height of 9 cm. About how much metal, to the nearest square centimeter, is needed to make 16 cans?

Step-by-step explanation:

A soup can is a cylinder.

The formula for volume of a cylinder is the following, V = Πr2h.

Given:

Height, h=12

Diameter, d=8

r = 8/2

= 4.

Now we can just plug the numbers into the formula

V = Π * (4) 2 * 12

= 603.19 cm^3

For 16 cans,

= 16 * 603.19

= 9650.97 cm^3 of metal
