Is there any way I can post a diagram?

hard to show diagrams.
Describe it in the best way you can 
The shaded region is between IKD
THere are to lnes opposite of each other. Then to parallel lines through those lines. Thers is a circle in the middle with a circumference of 20 pi. THen there is a triangle that connected to the outer lines to the right. the measure of the andgle formed is 1/2 10/3 pi. THen there is a shaded region that starts at the outer rim of the circle and ends at the lines.
Is that too confusing? 
Reiny?
