The **Weight or Mass of a Cone** calculator computes the * A geometric Cone *mass based on the mean density of the cone material (mD) and its volume as a function of the height (h) and the radius of the base (r).

**INSTRUCTIONS:** Choose the preferred units and enter the following:

- (
**h**) This is the height of the cone. - (
**r**) This is the radius of the based of the cone. - (
**mD**) This is the mean density of the material in the cone.

**Mass or Weight of a Cone:** The calculator returns the mass of the cone in kilograms. However, this can be automatically converted other mass or weight units via the pull-down menu.

This formula computes the volume of the geometric shape based on the input parameters. It then uses the formula for mass from volume and density:

where:

- V is the volume
- mD is the mean density.

to compute the mass. The mean density(mD) of many common substances, elements, liquids and materials can be found by clicking** HERE **(e.g. the mD of water is 1,000 kg/m^{3}).
