JEE Math Practice Question
Let the tangent to the circle x2 + y2 = 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 OPQ, then r2 is equal to :
- A.$${{585} \over {66}}$$
- B.$${{625} \over {72}}$$
- C.$${{529} \over {64}}$$
- D.$${{125} \over {72}}$$
