Answer:
The required amount of paper is 2715.23 .
Step-by-step explanation:
The cans of soup has a shape of a cylinder, so that;
The surface area around a cylinder = 2rh
Where: r is the radius of the can, and h is its height.
From the given question, diameter = 8 cm, then;
radius =
=
r = 4 cm
Surface area around one of the cans = 2 x x 4 x 9
= 226.2857
Surface area around one of the cans = 226.28
So that, the total amount of paper required to make labels around each of the 12 cans can be determined by:
12 x 226.2857 = 2715.4284
The required amount of paper is 2715.23 .
