Estimate the volume of a cone from radius and height.

Result

527.787566 cu in

Estimated cone volume from one-third times pi times radius squared times height.

Cone volume527.787566 cu in

Radius used6.000000 in

Height used14.000000 in

Formula basisV = (1/3)pi r^2 h

A radius of 6.000000 in and a height of 14.000000 in gives a cone volume near 527.787566 cu in.
The calculator uses the standard cone-volume formula directly from the radius and height entered.
Use the output for quick geometry, capacity, or comparison work whenever a circular cone is a reasonable model for the shape.

This is a standard geometry estimate. The result assumes a true circular cone and uses the same unit label for radius and height.

How it works

What the calculator is doing

Enter the radius and height of the cone and choose a unit label if you want one in the result.

The calculator applies the standard cone-volume formula.

It shows the resulting volume and the dimensions used in the estimate.

Understanding your result

This is a standard geometry estimate. It assumes a true circular cone and uses the same unit basis for radius and height.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Estimate the volume of a geometric cone

A quick volume result can help with classwork, sketches, or any shape comparison where a cone is a reasonable model.

Compare two cones with different proportions

Changing radius or height makes it easier to see which dimension is moving the volume more strongly.

Use it with other geometry tools

Cone volume often fits naturally beside surface-area, density, and other shape-measurement tools.

FAQ

Common questions

How is cone volume calculated here?

The calculator uses the standard formula one-third times pi times radius squared times height.

Why do radius and height need the same unit basis?

The volume formula combines both measurements directly, so the math only makes sense when they use the same unit basis.

What kind of cone does this assume?

It assumes a standard circular cone rather than an irregular or truncated shape.
