Ellipse Calculator

1. Semi-Major Axis (a): The longest radius.
2. Semi-Minor Axis (b): The shortest radius.
3. Calculate: Find the Area and Perimeter.

The Ellipse Calculator solves for the properties of an oval shape. Unlike a circle, an ellipse has two radii (semi-major and semi-minor axes).

It calculates the Area (π * a * b) and approximates the Perimeter (circumference) using Ramanujan's formula.
