The larger circle at the right has a radius 1.5 times the smaller circle. Compute the ratio fo the partial ring ABCD to the area of sector BOC.

 

The image is basically a circle inscribed in another circle. A and D are points on the bigger circle's circumference and B and C are points on the smaller circle's circumference. O is the center of both circles.
