Random Circles

Geometry Level 4

Jane is at the center of a circle. She moves \(4\sqrt{3}\) meters in a random direction, to a point which is still in the circle. Then, she chooses another random direction, and moves another \(4\sqrt{3}\) meters in that direction. Given that the probability that she is now outside of the circle is \(1/3\), what is the radius of the circle?
