Answer:

Step-by-step explanation:

You first need to find the surface area of a completely open cylinder. That formula is

SA=2\pi rh Using 3.14 for π, we find the area of the material that is needed to make this pipe:

SA = 2(3.14)(1)(30)

SA = 188.49 square feet.

If it costs $3.50 per square foot and you have 188.9 square feet, we multiply the cost per square foot times the number of square feet:

188.49(3.50) = $659.40, choice B.
