If two arcs of equal length subtend angles x and y at the centre, then x = y
If, in two circles, arcs of the same length subtend angles 600 and 750 at the centre, find the ratio of their radii.
If the arcs of the same length in two circles subtend angles 65∘ and 110∘ at the centre, then the ratio of the radii of the circles is
