So,
What we're going to do is to find the surface area of each can.
The formula to find the surface area of a can, is:
For the first can, we know that:
If we replace in the formula:
Now, we're going to find the surface area of the second can:
Replacing:
Therefore, the correct answer is C.
The company needs to compare the surface area of each can. The surface area of the first can is about 60 square inches, and the surface area of the second can is also about 60 square inches. Since both cans have approximately the same surface area, they will cost about the same for the company to produce.
