2 (06.02 MC) 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 it, and round your answer to the nearest hundredth. Provide an explanation and proof for your answer to receive full credit. (10 points)

259.05 ft²

Step-by-step explanation:

Surface area of a cylinder =  

(where r is the radius and h is the height)

Given:

Surface area of one fence post = (2 × 3.14 × (1/2)²) + (2 × 3.14 × 1/2 × 7)

                                                    = 1.57 + 21.98

                                                    = 23.55 ft²

Therefore, surface area of 11 fence posts = 11 × 23.55

                                                                    = 259.05 ft²

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).

it would be 4 over -2 divided by -1 over 3.

if you want a solution it would be 4

you flip it so it would be 4/-2 divided by 3/-1 then it would be 12/3 and you would simplify it to 4
