Answer:


Area = 339.29\ in^2

Explanation:

Given

See attachment

Required

Determine the total surface area

From the attachment:


r = 3\ in --- radius


h = 15\ in --- height

The total surface area:


Area = 2\pi r(r + h)

Substitute values for r and h


Area = 2\pi * 3(3 + 15)


Area = 2\pi * 3(18)

Remove bracket


Area = 2\pi * 3 * 18


Area = 2\pi * 54


\pi = (22)/(7)

So, we have:


Area = 2 * (22)/(7) * 54


Area = (2 * 22 * 54)/(7)


Area = (2376)/(7)


Area = 339.42

Hence, the closest is:


Area = 339.29\ in^2
