That music tho...

[@RupeshGesota]

I think the increasing red line on x axis (as the centre moves ahead) is not the circumference, but its the "projection of locus of center on x axis" which happens to be of same length as 2*pi when r=1; I think this construction wont show the actual circumference when r is not equal to 1...
