About Area of Ellipse

The Area of Ellipse Calculator is a fast, reliable, and easy-to-use tool that helps you calculate the area of an ellipse using its major and minor axes. Whether you're working on academic problems, engineering designs, or architectural layouts, this calculator provides quick and accurate results in just seconds.

What Is an Ellipse?

An ellipse is an oval-shaped curve, similar to a stretched circle. It has two main axes:

Major axis – the longest diameter
Minor axis – the shortest diameter

The area of an ellipse depends on the lengths of these two axes.

Formula for Area of an Ellipse:

The standard formula to calculate the area is:

Area = π × a × b

Where a is the semi-major axis (half of the longest diameter), b is the semi-minor axis (half of the shortest diameter), and π ≈ 3.1416.

Example Calculation:

If the major axis = 10 cm and the minor axis = 6 cm, then:

a = 5 cm, b = 3 cm
Area = 3.1416 × 5 × 3 ≈ 47.12 cm²

✅ So, the area of the ellipse is approximately 47.12 square centimeters.
