Hey(adsbygoogle = window.adsbygoogle || []).push({});

I’ve been given a problem to solve involving the minor segment of a circle. I know that the formula to solve for a segment is:

[tex]S = \frac{1}{2}r^2 (\theta - \sin \theta )[/tex]

However in this problem I’ve been given the segment area and the radius of the circle and been ask to find the minor angle. So far the best I have managed in rearranging the formula is:

[tex] \theta - \sin \theta = \frac{{2S}}{{r^2 }}[/tex]

I am confused on what to do with the sin theta part, so if somebody out there is able to help it will be greatly appreciated. Or am I wasting my time and this is not possible?

Many thanks in advance
