A) 4
B) \[2\sqrt{5}\]
C) 5
D) \[3\sqrt{5}\]
Correct Answer: C
Solution :
\[{{x}^{2}}+{{y}^{2}}+6x+6y-2=0\] Centre \[(-3,-3),\]radius \[=\sqrt{9+9+2}\] \[=\sqrt{20}\] Now, \[QC=\sqrt{{{(-3)}^{2}}+{{6}^{2}}}=\sqrt{45}\] In right \[\Delta CPQ\] \[PQ=\sqrt{45-20}=5\]You need to login to perform this action.
