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

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

If 5x-12y+10=0 and 12y-5x+16=0 are tangents of a circle, then radius of that circle is

If the straight lines x-4y + 7=0 and 3x - 12y + 11 =0 are tangents to a circle. Then, the radius of the circle is

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

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

If the lines 12x + 5y + 16 = 0 and 12 x+ 5y - 10 = 0 are tangent to a circle then the radius is :

The lines 5x - 12 y =5 and 10 x- 24y+3=0 are tangents to the same circle. Then the diameter 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
