SUMMARY
The Nested Ball Problem requires proving that the distance between the centers of two balls, represented as d(x,y), is less than or equal to the difference in their radii, r_big - r_small. The solution involves applying the triangle inequality, which shows that d(x,y) ≤ r_big + r_small. A visual representation of the two circles can clarify why the smaller circle cannot be contained within the larger circle when the distance exceeds r_big - r_small.
