Usually "width" of a cylinder means the diameter. If width = 2 (so radius r = 1) and height h = 3:
Surface area = lateral + 2 bases = 2πrh + 2πr^2 = 2πr(h + r)
= 2π(1)(3 + 1) = 8π ≈ 25.13 (square units).
If by "width" you meant the radius = 2, the surface area would be 20π ≈ 62.83. Which did you mean?
