Which of the following is/are true ? The circles x^(2)+y^(2)-6x+6y+9=0 and x^(2)+y^(2)+6x+6y+9=0 are such that :

Which of the following is/are true ? The circles x^(2)+y^(2)-6x+6y+9=0 and x^(2)+y^(2)+6x+6y+9=0 are such that :

Given that x^(2)+y^(2)=14x+6y+6, find the largest possible value of the expression E=3x+4y.

The centre of similutude of the circles x^(2)+y^(2)-2x-6y+6=0, x^(2)+y^(2)=1 is

The centres of similutude of the circles x^(2)+y^(2)-2x-6y+6=0, x^(2)+y^(2)=1 is

The two circles x^(2) + y^(2) -2x + 6y + 6 = 0 and x^(2) + y^(2) -5x + 6y + 15 = 0

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

The radius of circle having centre at (2,1) and whose on of the chord is diameter of the circle x^(2)+y^(2)-2x-6y+6=0 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:
