Hmm.. Not sure if this way works! 2x4y9=0 & 6x12y+7=0 = tangents to the same circle. That have the same slope => perpendicular distance between the two lines is the diameter of the circle. Half of the diameter is the radius :\ I think this is not a smart way to solve your problem though :(

as @Callisto rightly stated..the lines are parallel, distance between them gives diameter, half of diameter is radius! voila !
