A) A point
B) A circle
C) A straight line
D) Two straight lines
Correct Answer: B
Solution :
The locus of the centres of all circles of given radius r, in the same plane, passing through a fixed point \[P({{x}_{1}},{{y}_{1}})\] is ? 'A circle, whose radius is r and centre is the given fixed point \[P(x,y)'\] Its equation will be \[{{(x-{{x}_{1}})}^{2}}+{{(y-y)}^{2}}={{r}^{2}}\]You need to login to perform this action.
