If the shortest distance from \((2,-14)\) to the circle \(x^2+y^2+6 x+4 y-12=0\) is \(d\) and the length of the tangent drawn from the same point to the circle is \(l\), then \(\sqrt{d+l}=\)
- A 13
- B \(2 \sqrt{5}\)
- C 12
- D 5
Answer & Solution
Correct Answer
(B) \(2 \sqrt{5}\)
Step-by-step Solution
Detailed explanation
Given circle, \(x^2+y^2+6 x+4 y-12=0\) Here, centre is \(O(-3,-2)\) and radius \(=\sqrt{9+4+12}=\sqrt{25}=5\) Shortest distance of the point \(P(2,-14)\) to the circle is…
