If one of the diameter of the circle `x^(2)+y^(2)-2x-6y+6=0` is a chord to the circle with centre (2, 1), then the radius of the bigger circle is

If one of the diameters of the circle x^2+y^2-2x-6y+6=0 is a chord to the circle with centre (2,1), then the radius of the bigger circle is

If one of the diameters of the circle x^(2)+y^(2)-2x-6y+6=0 is a chord to the circle with centre (2,1), then the radius of circle is:

If one of the diameters of the circle x^2+y^2-2x-6y+6=0 is a chord to the circle with centre (2,1), then the radius of the circle is

If one of the diameters of the circle x^(2)+y^(2)-2x-6y+6=0 is a chord to the circle with center (2,1) ,then the radius of the circle is

If one of the diameters of the circle x^2+ y^2-2x-6y + 6=0 is a chord to the circle with centre (2, 1), then the radius of the circles is :

If one of the diameters of the circle x^2+y^2-2x-6y+ 6 = 0 is a chord to the circle with centre (2, 1), then the radius of circle is:

If one of the diameters of the circle x^(2)+y^(2)-2x-6y+6=0 is a chord to the circle with centre at (2,1) show that the radius of the circle is 3.

If one of the diameters of the circle x^2+y^2-2 x-6 y+6 =0 is a chord to the circle with centre at (2,1) then the radius of the circle is equal to.
