Chords of Concentric Circles
Posted:

Ok.. here's a rough problem. If anyone can help me, please reply...
There are two concentric circles such that the radius of the smaller plus the radius of the larger is 36. A chord of the larger circle is trisected by the smaller; that is, it must pass through the smaller circle. This chord is length 36 also. What is the radius of the large circle?
