# Cone Volume Calculator

This cone volume calculator can help in solving your school problems or can answer your weird day-to-day questions. How much ice cream does it fit into my cone? How much cream can I put into the pastry bag? Or what's the volume of my conical champagne glass? If these are the questions which bother you every day, keep reading!

## Cone volume formula

A cone is a solid that has a circular base and a single vertex. To calculate its volume you need to multiply the base area (area of a circle: π * r²) by height and by 1/3:

`volume = (1/3) * π * r² * h`

A cone with a polygonal base is called a pyramid.

## How to calculate the volume of a cone?

Let's calculate how much water does it fit into the conical part of the funnel.

**Determine the height of the cone**. For our funnel, it's**4 in**.**Enter the base radius**. It may be equal to**3 in**.**The volume of the cone**is displayed in the calculator - in our case, it's**37.7 cu in**.

Remember that you can change the units to meet your exact needs - click on the unit and select from the list. If you need simple volume unit conversion, check out our volume converter tool.

## Truncated cone volume (volume of frustum)

A truncated cone is the cone with the top cut off, with a cut perpendicular to the height. You can calculate frustum volume by subtracting smaller cone volume (the cut one) from the bigger base one, or use the formula:

`volume = (1/3) * π * depth * (r² + r * R + R²)`

, where`r`

is a radius of the base of a cone, and`R`

of top surface radius

An example of the volume of a truncated cone calculation can be found in our potting soil calculator, as the standard flower pot is a frustum of a cone.

## Oblique cone volume

An oblique cone is a cone with an apex that is not aligned above the center of the base. It "*leans*" to one side, similarly to the oblique cylinder. The cone volume formula of the oblique cone is the same as for the right one.
