Answer:
4747.68 sq. cm
Step-by-step explanation:
First find the circumference of the circular part of the can. The equation is C=2pi(r). Fill in the values and the circumference should come out to be 37.68. Remember you are trying to cover the can, so one straight line won't cut it. You have to multiply by 7, or the height of the can.
Then you have it, 263.76 sq. cm.... to cover one can. Since they are asking for 18, multiply by 18 and you will have 4747.68.
