Question

& If the circle x + y + 4x + 22y +C =0 bisects the crounderare of the circle x² + y2_2ut 18 y-dao , then find card. 6​

Answer 1

Answer:

The common chord must be a diameter of the second circle.

The equation to the common chord is

S

1

−S

2

=0, i.e., 6x+14y+(c+d)=0.

The centre of the second circle (1,−4) lies on it,

∴6(1)+14(−4)+c+d=0

∴c+d=50.
