sveta [45]

Answer:

Step-by-step explanation:

A soup can is a cylinder.

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

Height, h=12

Diameter, d=8

r = 8/2

Now we can just plug the numbers into the formula

V = Π × (4)2 × 12

For 16 cans,

= 16 × 603.19

= 9650.97 cm^3 of metal
