Question

What is the formula for finding the area of an oval?

Answer 1

`pixx"semi-major axis"xx"semi-minor axis"`

Explanation:

Similar to how the area of a circle is `A=pir^2`, an oval (ellipse) is similar, except for that it has the equivalent of two radii, the semi-minor and semi-major axes.

The `r^2` in the circle area equation is replaced with the product of the lengths of the axes:

`A_"ellipse"=piab`
