To start, you find the area of the circle.   A=pi r^2

Since we know 120 degrees is a 1/3 of a circle, we multiply the are by 1/3

at this point we have the area of the specific section and we now need to remove the area of the white section. The triangle present is annoying so we will draw a line that cuts the triangle in 1/2. This will give us to triangles that both have an angle of 60 degrees.

At this point we should now see to right triangles! since we know the angle and the hypotenuse (radius), we do some trig. to find the base of the triangle.

1/2 (base)(height)= Area of triangle. Find the base and then used pythagoreans theorem
to solve for height.

This was a very quick hodgepodge answer but the approach is correct.
