`A = 1/3 * "b" * "h" `

Enter a value for all fields

The **Parabolic Area (Concave)** calculator computes the area (yellow in the diagram) outside of a parabola within a rectangle defined by a (b) base and (h) height.

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

- (
**b**) This is the length of the base. - (
**h**) This is the height

**Area (A):** The calculator returns the area in square meters. However, this can be automatically converted to compatible 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.
