How to Use This Calculator
- Enter the length of the semi-major axis (a) in your preferred unit (e.g., meters, centimeters, etc.). This is the longest radius of the oval.
- Enter the length of the semi-minor axis (b) in the same unit as the semi-major axis. This is the shortest radius of the oval.
- Click the "Calculate" button to compute the area.
- The calculator will display the area in the same unit squared (e.g., square meters, square centimeters).
- Click "Reset" to clear all inputs and start over.
Understanding Oval Geometry
An oval (or ellipse) is a geometric shape that resembles a stretched circle. It's defined by two axes:
- Semi-Major Axis (a): The longest radius from the center to the edge.
- Semi-Minor Axis (b): The shortest radius from the center to the edge.
Mathematical Formula
The area of an oval (ellipse) is calculated using the formula:
Area = π × a × b
Where π (pi) is approximately 3.14159, and a and b are the lengths of the semi-major and semi-minor axes respectively.
Real-World Applications
The area of an oval calculator is useful in various fields including:
- Architecture and design for elliptical rooms or structures
- Engineering for calculating cross-sectional areas of elliptical components
- Physics for understanding orbits (planets follow elliptical paths)
- Art and design for creating elliptical patterns
