Let \(\Delta ABC\) be a triangle with vertices \( A=(0,0), B=(6,0), C=\big(3,3\sqrt{3}\big),\) and \(\Delta PQR\) the pedal triangle of \(\Delta ABC.\)

The sum of the circumradius of \( \Delta ABC\) and inradius of \( \Delta PQR\) can be expressed as \(\frac{a\sqrt{b}}{c}\) for positive integers \(a,b,\) and \(c,\) where \(a,c\) are coprime and \(b\) is square-free.

Find \(a\times b\times c\).
