Answer 1

I don't see the cylinder's dimensions in your message. Can you tell me the radius (or diameter) and the height — or paste the picture of the problem? Also confirm whether the problem asks for the total surface area (including the two circular ends) or only the lateral area.

If it's the total surface area, use this formula:
SA = 2πr^2 + 2πrh = 2πr(r + h).
With π = 3.14 that becomes SA = 6.28·r·(r + h).

If you give r and h I will compute the value and round to the nearest tenth (and pick the matching multiple-choice answer).
