How to use Cylinder Calculator
For a right circular cylinder, volume is πr²h. Lateral surface area is 2πrh, and total closed surface area adds the two circular ends.
- Enter base radius, height.
- Check that the input follows the stated limits and uses consistent units.
- Run the calculator, review the result, then copy or download it.
Good to know
- Positive radius and height in matching units are required. No wall thickness, end caps, material density, or tank fill level is modeled.
- Decimal inputs have at most 120 characters and magnitude from 1e-100 to 1e15, or zero. Floating-point results are rounded to 12 significant digits; extreme derived results may underflow or be rejected. Exact integer results are identified separately.
Common questions
What calculation does Cylinder Calculator perform?
For a right circular cylinder, volume is πr²h. Lateral surface area is 2πrh, and total closed surface area adds the two circular ends.
Does total area include both ends?
Yes. The total is lateral area plus 2πr². Lateral area is also shown separately.
