Let the tangent to the circle $\displaystyle x^2+y^2=25$ at the point $\displaystyle \mathrm{R}(3,4)$ meet $\displaystyle x$-axis and $\displaystyle y$-axis at points P and Q , respectively. If r is the radius of the circle passing through the origin O and having centre at the incentre of the triangle OPQ, then $\displaystyle \mathbf{r}^2$ is equal to :
