# Radius of a ball

**Geometry**Level pending

A circle has a radius \(R\) and a circumference \(l\). If we increase the radius of this circle by 1 unit, then the ratio between the new circumference and the old circumference of this circle can be expressed as \( A + \dfrac B{CR } \), where \(A,B\) and \(C\) are integers with \(B,C\) coprime positive integers.

Submit your answer as \(A+B+C\).
