The **Mass or Weight of a Paraboloid** calculator the weight or mass of a paraboloid of revolution around an axis of length (a) of a width of (b) with a mean density (mD). * A Paraboloid *

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

- (
**a**) - This is the length along the axis. - (
**b**) - This is the length from the axis to the edge of the parabola. - (
**mD**) Density of the material in the paraboloid (CLICK HERE).

**Mass of the Paraboloid (M):** The calculator returns the mass of the paraboloid in kilograms. However, this can be automatically converted to other mass and weight units via the pull-down menu.

**Parabola Formula**: This computes the y coordinate of a parabola in the form y = a•x²+b•x+c**Parabolic Area**: This computes the area within a section of a parabola**Parabolic Area (Concave)**: This computes the outer area of a section of a parabola.**Parabolic Arc Length**: This computes the length a long a segment of a parabola.**Paraboloid Volume**: This is the volume of a parabola rotated around an axis (i.e. paraboloid)**Paraboloid Surface Area**: This is the surface area of a paraboloid.**Paraboloid Weight**: This is the weight or mass of a paraboloid.**Ballistic Flight Parabolic Equation**: This provides the formula of the parabola that matches a ballistic flight.

This formula computes the volume of the geometric shape based on the input parameters. With the computed volume, this formula then executes the simple equation below to compute the approximate mass of the object.

The mean density (mD, μD or ρ) of many common substances, elements, liquids and materials can be found by clicking** HERE **(e.g. the μD_{(water)} is 1000.0 kg/m³).
