PL HELP Ellis is painting wooden fenceposts before putting the in his yard. The are each 5 feet tall and have a diameter of 1 foot. There are 10 fenceposts in all. How much paint will Ellis need to paint all the surfaces of the 10 fenceposts? Use 3.14 for pi, and round your answer to the nearest hundredth. Provide an explanation and proof for your answer to receive full credit.

259.05

Step-by-step explanation:

height is: 5

Radius is: 0.5, because half of 1(diameter) is your radius.

10 in total.

Let's find the circumference and then multiply by the height to get the surface area of the cylinder. We then multiply it by the total of the fence posts.

Formula of a circumference:

2π4

In this case:

2(you just use this number whenever finding circumference) x 3.14(pi) x 0.5(radius) = 3.14 is your circumference.

Now we multiply the circumference by the height:

3.14(circumference) x 5(height) = 15.7

Now we multiply it by the many times there are fence posts:

15.7(surface area of the cylinder) x 10(total fence posts) = 157 ft^2 is your answer.
