Frequently Asked Questions
What is the ellipse area formula?
Area = π × a × b, where a is the semi-major axis and b is the semi-minor axis.
What are semi-major and semi-minor axes?
The semi-major axis is half the longest diameter, and the semi-minor axis is half the shortest diameter of the ellipse.
How does this relate to circle area?
A circle is a special ellipse where a = b = r, making the formula π × r × r = πr².
