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.

- Surface Area: cone surface area based on cone height and cone base radius
- Volume: cone volume based on cone height and cone base radius
- Mass: cone mass or weight as a function of the volume and mean density
- Frustum Surface Area: cone frustum surface area based on the two heights and two radii
- Frustum Volume: cone frustum volume based on the two heights and two radii
- Frustum Mass: cone frustum weight or mass based on the cone frustum volume and mean density
- Shell Volume: cone shell volume a.k.a. hollow cone volume
- Shell Mass: cone shell mass or weight a.k.a. hollow cone mass.

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}).
