If `5x-12y+10=0` and `12y-5x+16=0` are two tangents to a circle, then the radius the circle, is

If 2x-4y=9 and 6x-12y+7=0 are parallel tangents to circle, then radius of the circle, is

The lines 12 x-5y-17=0&24 x-10 y+44=0 are tangents to the same circle. Then the radius of the circle is: 1 (b) 3/2 (c) 2 (d) none of these

If the lines 5x - 12y = 5 " and " 10x - 24y + 3 = 0 are tangents to the same circle , then diameter of the circle is

If lines 12 x + 5y + 16 = 0 " and " 12 x + 5y - 10 = 0 both touch the same circle , then radius radius of this circle is

The line 2x-y+1=0 is tangent to the circle at the point (2,5) and the centre of the circles lies on x-2y=4. The radius of the circle is :

The line 2x-y+1=0 is tangent to the circle at the point (2,5) and the centre of the circles lies on x-2y=4 The radius of the circle is:

The line 2x-y+1=0 is tangent to the circle at the point (2,5) and the centre of the circles lies on x-2y=4. The radius of the circle is
