This is a geometry problem more than coordinate geometry

The circle is of radius 3

the point is at distance 5 from the circle.

The length of the tangent will be 4.

We can, using this geometry find the length fo the chord!

THat will fix this easily :)

If you are nto able to get the final answer do ask ... :)
