Let r be the radius and h the height.
- Lateral (curved) surface area: A_lateral = 2πrh
- Area of both circular bases: A_bases = 2πr^2
- Total surface area (closed cylinder): A_total = 2πr^2 + 2πrh = 2πr(r + h)
If the cylinder is open at one end, A = πr^2 + 2πrh. If both ends are open, A = 2πrh.
Units: square units (e.g., cm²).
