If the label of a can of yams were cut off and laid flat, which expression would give the area, A, of the label with the measurements shown?


A.) A = π • r2 • h

B.) A = π • r • h

C.) A = 2 • π • r • h

D.) A = 2 • r • h

Respuesta :

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.
