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

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
