Triangle $XYZ$ has an inradius of $3$ and a circumradius of $12$. If $3\cos{Y} = \cos{X} + \cos{Z}$, determine the area of triangle $XYZ$ in the form $\frac{p\sqrt{q}}{r}$, where $p, q,$ and $r$ are positive integers such that $p$ and $r$ are relatively prime, and $q$ is not divisible by the square of any prime. Compute $p+q+r$.
