Question

The radius of the circle which touches y -axis
at (0,0) and passes through the point (b,c) is​

Answer 1

Answer:

As (0,0) and (0,1) lies inside the circle x

2

+y

2

=16 .

So the circle will touch the given circle internally.

And by symmetry its diameter will be equal to given radius of given circle.

Radius of given circle =

16

=4

So radius of our circle =

2

4

=2

So, option B is correct.
