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

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

The total nom of  code that can be used is equal to 5+3 = 8

The answer is in the image 

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales
