Express answer in exact form. show all work for full credit. a segment of a circle has a 120 arc and a chord of 8 sq root 3. find the area of the segment.

Let be the angle of an arc,   and r be the radius of the circle.

Then by the cosine rule,

1. Find the area of the sector. Since then

2. Find the area of the triangle formed by two radii and chord:

3. The area of the segment is

b because it contains 40% of the possible results from the random list.
