Find the total surface area.
Ede4ka [16]

Hey love! <3

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 />

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

The area is equal to 230 CM.
area for rectangle :
area = width times length
area = 7 x 20 = 140CM
area for triangle:
area = 1/2 times base times height
area = 1/2 x 20 x 9 = 90CM

ADD:
140+90 = 230 CM
