This tool calculates the area of an ellipse by simply entering the long and short half axes of the ellipse and clicking the calculate button.
Uses of the Oval Area Calculator
The Oval Area Calculator can be used to calculate the area of an ellipse for further calculations or analysis.
What is the formula for the area of an oval?
{ \color{Orange} S=\pi ab }
- a and b denote the lengths of the long and short semi-axes of the ellipse, respectively.
- π is the circumference, usually taken as 3.14159.
How is the ellipse area formula used in life?
Suppose you have an elliptical flat surface with a long semi-axis of 5 metres and a short semi-axis of 3 metres. Then, according to the ellipse area formula, the area of the plane is:
{\color{Orange} S=\pi ab = \pi \times 5(m) \times 3(m) = 47.1 \text{㎡}}
