How to use this tool

  1. Enter bottom radius, top radius, height.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Volume = πh(r1² + r1r2 + r2²)/3.

A WORKED EXAMPLE

Using bottom radius = 4 m, top radius = 2 m, height = 5 m, the result is 146.607657 m³. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

Use the indicated units consistently. Ideal shapes are assumed; dimensions must describe the same object. Display rounding does not increase measurement precision.

Common questions

Which inputs does this calculation need?

Find the capacity between parallel cuts of a cone. Enter bottom radius in m, top radius in m, height in m. The filled example is editable and is not a saved personal record.

How should I interpret the result?

Use the indicated units consistently. Ideal shapes are assumed; dimensions must describe the same object. Display rounding does not increase measurement precision.
