## About This Tool

The online Area of An Ellipse Calculator is used to calculate the area of an ellipse.

## Ellipse

In geometry, an ellipse is a regular oval shape, traced by a point moving in a plane so that the sum of its distances from two other points (the foci) is constant, or resulting when a cone is cut by an oblique plane that does not intersect the base.

## Formula

The following is the calculation formula for the area of an ellipse:

Area = πab

Where:

a = semi-major axis length of an ellipse

b = semi-minor axis length of an ellipse

π = 3.141592654
