# Area of ellipse calculator

To calculate the area of an ellipse, you need to know its semi-major axis (a) and semi-minor axis (b). The formula to calculate the area of an ellipse is:

**Area = πab**

where π is the mathematical constant pi (approximately equal to 3.14).

## To use the formula, follow these steps:

- Measure the length of the semi-major axis (a) of the ellipse. This is the distance from the center of the ellipse to the furthest point on its circumference along its longest axis.
- Measure the length of the semi-minor axis (b) of the ellipse. This is the distance from the center of the ellipse to the furthest point on its circumference along its shortest axis.
- Multiply a by b to get the value of ab.
- Multiply ab by π to get the area of the ellipse.

Alternatively, you can use an online calculator to find the area of an ellipse by entering the values of a and b.

## what is the Area of ellipse?

The area of an ellipse is the total region that is enclosed by the perimeter of an ellipse. The formula to calculate the area of an ellipse is:

**Area = π x a x b**

where “a” and “b” are the semi-major and semi-minor axis of the ellipse, respectively, and π is the mathematical constant pi (approximately equal to 3.14159).
