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.

The answer to your question is 414.48 ft²

Step-by-step explanation:

Data

height = 6 ft

diameter = 1 ft

# of fence posts = 12

amount of paint = ?

Formula

Area of a cylinder = πr² + 2πrh

Process

1.- Find the area of 1 cylinder

Area = (3.14 x 0.5) + (2 x 3.14 x 0.5 x 6)

Area = 15.7 + 18.84

Area = 34.54 ft²

2.- Calculate the area of 12 fencepost

Total area = 12 x 34.54

                = 414.48 ft²

next time before you ask a question look if some one else has answered it first

two data sets with the same median will not have the same varaibility

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
