In circle x^(2)+y^(2)-"Kx"-12y+4=0 touches X-axis, then K = . . . .

The circle 4x^(2)+4y^(2)-12x-12y+9=0

The circle 4x^(2)+4y^(2)-12x-12y+9=0

Statement I The circle x^(2) + y^(2) - 6x - 4y - 7 = 0 touches y-axis Statement II The circle x^(2) + y^(2) + 6x + 4y - 7 = 0 touches x-axis Which of the following is a correct statement ?

Prove that the circle x^(2) +y^(2) - 6 x -2 y + 9 = 0 (i) touches the x-axis, (ii) lies entirely inside the circle x^(2) + y^(2) = 18 .

Observe the following statements I. The circle x^(2)+y^(2)-6 x-4 y-7=0 touches y axis II. The circle x^(2)+y^(2)+6 x+4 y-7=0 touches x -axis which of the following is a correct statement?
