Answer:
The right answer is A = 49.6 π ft^2
Step-by-step explanation:
<em><u>(Let pi = 3.1415926535898)</u></em>
<em>The formula for calculating the surface area of a cylinder is A=2πrh+2πr^2</em>
<em>So if r = 4 ft</em>
<em>and h = 2.2 ft</em>
<em>A= 2π(4)(2.2)+2π(4)^2</em>
<em>Once we've plugged in our formulas our final surface area is A =</em><em> 49.6 π ft2</em>

<em>Hope this helped you calculate the surface area! ◃┆◉◡◉┆▷ Sincerely, Kelsey from Brainly.</em>

Legnth of 1 section times number of sections=number of feet needed=6*12=72
72ft=850
divie both sides by 72
1ft=11.8055555
1 ft=$11.81
