Ellis is painting the wooden fenceposts 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 surface of the 11 fenceposts? use 3.14 for pie , and round your answer the nearest hundredth.

the answer to your question is: she will need enough paint to paint 164.9 ft².

step-by-step explanation:

data

height = 5 ft

diameter = 1 ft

number of fenceposts = 10

π = 3.14

formula

al = 2πrh + πr²

process

radius = diameter / 2

radius = 1 / 2 = 0.5 ft

al = 2(3.14)(0.5)(5) + (3.14)(0.5)²

al = 15.7 + 0.785

al = 16.49 ft²

but there are 10 fenceposts, then:

final area = 10 x 16.49

                = 164.9 ft
