look at the triangle formed by the chord and the radii.

Don't you have an equilateral triangle ?

That would make the central angle = 60°

So the area of the SECTOR is 1/6 of the area of the circle.

If you subtract the area of the equilateral triangle you would be left with the area of the segment

In your previous post, I showed you how to find the height of such a triangle.

So the problem should be easy for you now.
