Answer» Let the tangent to the circle $x^{2} + y^{2} = 25$ at the point $R (3, 4)$ meet $x -$ axis and $y -$ 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 $O P Q,$ then $r^{2}$ is equal to :
