How to use this calculator
Calculate cylinder volume and surface area from radius and height.
How the calculation works
- Enter radius and height.
- The circular base area is calculated.
- Volume and surface area are displayed.
Formula
Volume = πr²h. Surface area = 2πr(r + h).
Example
A cylinder with radius 1 and height 1 has volume π.
Understanding your result
Use the output as a practical starting point, then review it before using it in an important workflow.
Assumptions and limitations
- Use consistent units for radius and height.
- Results are generic geometric estimates.
