The correct answer is A = 2 x pi x r x h. So basically the answer is C. Hope I helped! :)

Answer:

C.) A = 2 • π • r • h

Step-by-step explanation:

The distance around a circle is the circumference, and the formula for it is

C = 2πr.

Taking the label off of the can and stretching it out makes this distance around the circle the length of the rectangular label.

To find the area of a rectangle, we multiply length and width; we know the length is 2πr. The width of the rectangle is the height of the can; this makes the area

A = 2πrh.
