How do I calculate the volume of a truncated cone?

To find the volume of a truncated cone (frustum), input the radii of both the larger and smaller bases along with the height. The calculator subtracts the volume of the smaller cone from the larger cone to determine the result.

Can I change the units for the volume output?

Yes, the calculator allows you to click on the unit and select from a list of available options to match your exact needs.

What if I only know the slant height and radius?

The tool recommends using a slant height calculator to determine the vertical height first, as the volume formula requires the perpendicular height.

Does the calculator provide the formula used?

The interface displays the cone volume formula (one-third times pi times radius squared times height) and explains the relationship to base area, helping users understand the calculation.

About this tool

What Cone Volume Calculator does

The Cone Volume Calculator on Omni Calculator determines the volume of a standard cone and a truncated cone (frustum) using geometric dimensions. Users input height and base radius, or the two radii and height for a frustum, to receive instant volumetric results. Beyond basic calculations, the tool addresses practical questions—such as how much ice cream fits in a cone or how much cream a pastry bag can hold—and supports unit conversions for the output. It also links to related calculators for surface area and cylindrical volumes, providing a broader context for three-dimensional shape problems.
