# Difference

**Geometry**Level 3

The difference between the area of the \(\color{#ee7600}{\text{orange}}\) shaded region and the \(\color{blue}{\text{blue}}\) shaded region can be written as \(a(b-a\pi )\) for integers \(a\) and \(b\). Let the digit sum of \(b\) be \(B\). Then find the remainder of \[\large\overline { Baa } \div B \]
