How it works
Multiply the circular base area by the vertical height for a right cylinder; slanted oblique cylinders need a different model.
Formula
V = πr²h
How to use Volume of a Cylinder Calculator
- Enter circular base radius and cylinder height.
- Use diameter mode if offered, converting to radius internally.
- Read cubic volume.
- Link to cone volume (one-third of same base and height) for comparisons.
Worked examples
Concrete numbers and cases you can check against the tool above.
Tank r = 0.5 m, h = 2 m
V = π×0.25×2 ≈ 1.57 m³ of water when full.
When to use Volume of a Cylinder Calculator
Cans, silos, and pipes are cylinders. Volume drives fill levels and shipping fluid weights.
Common use cases
- How much water fits in a rain barrel.
- Concrete for a round column form.
- Engine displacement intuition (related geometry).
Inputs and outputs
- Radius (or diameter) and height

Frequently asked questions
- Horizontal cylinder partial fill?
- Full-volume formula assumes filled to the top; partial fill needs segment formulas not covered here.
- Units?
- If radius and height are in meters, volume is cubic meters.
- Relation to cone?
- A cone with same base and height has exactly one-third this volume.
