Question

Ellis is painting wooden fenceposts before putting them in his yard. They are each 6 feet tall and have a diameter of 1 foot. There are 12 fenceposts in all. How much paint will Ellis need to paint all the surfaces of the 12 fenceposts? Use 3.14 for π, and round your answer to the nearest hundredth. Provide an explanation and proof for your answer to receive full credit.

Answer 1

Using the surface area of a cylinder, it is found that Ellis will need 263.89 squared feet of paint to paint all the posts.

What is the surface area of a cylinder?

The surface area of a cylinder of radius r and height h is given by:

$S = 2\pi r(r + h)$

In this problem, the measures are h = 6 ft, r = 0.5d = 0.5 ft, and there are 12 posts, hence the combined surface area in feet squared is given by:

$S = 12 \times 2\pi \times 0.5(0.5 + 6.5) = 263.89$
