Acan of soup is 3 inches in diameter and 5 inches in height. how much paper is needed to make a label for the soup can?

a.
60 sq. in
c.
55 sq. in
b.
47 sq. in
d.
37 sq. in

The answer is B(47 sq. in). I assume the paper does not cover the circles on the top and bottom of the can, so what you have left is the cylindrical piece. If you're covering something, you're finding the surface area, not the area of the can. Therefore, you must use the formula 2*pi*r*h. (R is the radius, which is 1.5, and h is the height, which is equal to 5). Plug in the radius and height, and you end up with about 47 square inches. Hope this helps!
