In the xy-plane, the point (-2, -3) is the center of a circle. The point (-2, 1) lies inside the circle and the point (4, -3) lies outside the circle. If the radius r of the circle is an integer, then r =

5
dis b/n centre and inner point is 4 and that b/n center and outr point is 6
5 is the only int value b/n 4 and 6
dis b/n centre and inner point is 4 and that b/n center and outr point is 6
5 is the only int value b/n 4 and 6
radius or circle is greater than 4 and less than 6
so it is 5
option B
distance between O(-2,-3) and A(-2,1) = 4. Since, A is in the circle, radius >4
distance between O(-2,-3) and B(4,-3) = 6. Since, B is outside circle radius <6
so it is 5
option B
distance between O(-2,-3) and A(-2,1) = 4. Since, A is in the circle, radius >4
distance between O(-2,-3) and B(4,-3) = 6. Since, B is outside circle radius <6
