I'll assume "width" means the diameter = 2, so the radius r = 1 and height h = 3.
Surface area of a cylinder = 2πr^2 + 2πrh.
Plugging in r = 1, h = 3 and π = 3.14:
2πr^2 + 2πrh = 2(3.14)(1^2) + 2(3.14)(1)(3) = 6.28 + 18.84 = 25.12
So the surface area is 25.12 square units.
(If by "width" you meant the radius = 2 instead, the surface area would be 20π ≈ 62.8.)
