Cylinder Surface Area Calculator
Enter the radius and height of a cylinder to calculate its total surface area.
Cylinder Surface Area Calculator
Calculate the total surface area of a cylinder from its radius and height.
This is a straightforward geometric calculation; ensure radius and height use the same unit of measurement, as the results will be in that unit squared (area) or cubed (volume).
A cylinder’s total surface area combines the area of its two circular ends and the curved lateral surface that wraps around its side.
Example
- With the default values shown above, this calculator returns: Lateral Surface Area ≈ 314.159; Total Surface Area ≈ 471.239; Volume ≈ 785.398.
Frequently Asked Questions
What is the formula for total surface area?
Total surface area = 2πr(r + h), which combines the two circular end caps (2πr²) and the curved lateral surface (2πrh).
Does this also give volume?
Yes — the calculator also computes the cylinder’s volume (πr²h) as a bonus result, since it uses the same two inputs.
