Cylinder Surface Area Calculator
Compute the total surface area of a cylinder: A = 2πr(r + h).
Input Data
Base radius.
Cylinder height.
Results
245.0442
Cylinder surface area = 2πr(r+h) = 245.0442.
At a glance:Total cylinder surface area A = 2πr² + 2πrh = 2πr(r + h), including both bases and the lateral area.
Formula
A = 2πr(r + h).
How to Use
- Enter radius r and height h.
- The tool returns total surface area A.
Case Studies
r=3, h=10 → 245.04
A = 2π·3·13 ≈ 245.04.
FAQ
Includes bases?
Yes, both circular bases and the lateral area.
Lateral only?
Lateral area = 2πrh; this tool gives the total.
