A) \[\sqrt{3}\]
B) \[\sqrt{5}\]
C) \[\sqrt{7}\]
D) \[\sqrt{11}\]
Correct Answer: C
Solution :
The centre of the sphere \[{{x}^{2}}+{{y}^{2}}+{{z}^{2}}-2y-4x-11=0\]is \[(0,1,2)\]and radius \[r=\sqrt{{{0}^{2}}+{{1}^{2}}+{{2}^{2}}+11}\] \[\Rightarrow \] \[r=OP=4\] Given equation of plane is \[x+2y+2z-15=0\]You need to login to perform this action.
