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.

Answer 1

TA_{1 post} = 2(π)(0.5)² + 6π

TA_{12 posts} = (12)((2)(π)(0.5)² + 6π))

The amount of paint per square foot is not given.
