How to use the calculator
- Enter the length of the semi-major axis (a) in your preferred unit (e.g., meters, centimeters)
- Enter the length of the semi-minor axis (b) in the same unit as the semi-major axis
- Click the "Calculate" button to compute the area
- The result will be displayed in square units (e.g., square meters, square centimeters)
Understanding the formula
The area of an ellipse is calculated using the formula: Area = π × a × b, where:
- π (pi) is a mathematical constant approximately equal to 3.14159
- a is the semi-major axis (the longest radius of the ellipse)
- b is the semi-minor axis (the shortest radius of the ellipse)
Practical applications
An ellipse area calculator can be used in various fields including:
- Engineering and architecture for designing elliptical structures
- Physics for calculating areas of elliptical orbits
- Art and design for creating elliptical shapes
- Geography for mapping ellipsoidal Earth models
