Ellis is painting wooden fenceposts before putting them in his yard. They are each 7 feet tall and have a diameter of 1 foot. There are 11 fenceposts in all. How much paint will Ellis need to paint all the surfaces of the 11 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.

If you aren't painting the bottom of the fence posts, then :

(7*3.14)(11) + ((1/2)^2)(11)(3.14) =

(7*3.14)(11) is the lateral surface area; ((1/2)^2)(11)(3.14) is the area of the top base

(3.14)(11)(7.25) =

250.415 -->

250.42 ft^2 have to be painted.

If you are painting the bottom of the fence posts, then:

(7*3.14)(11) + (2)((1/2)^2)(11)(3.14) =

(7*3.14)(11) is the lateral surface area; (2)((1/2)^2)(11)(3.14) is the area of the top and bottom bases

(3.14)(11)(7.5) =

259.05 -->

259.05 ft^2 have to be painted.

the answer is mp
