I'm not trying to muddy the water, but I can see where there would be a little confusion here.



Should we all agree that you go by the width of the bands on the very top?



I will give three scenarios.



(1) if the bands were straight across and the widths were the same for the black and white on the top, then that would be the same down the sides, (SA = 2 × pi × r2 2 × pi × r × h) (total area of a cylinder) hence- the 50/50.



(2) It the black and white were the same on top, but had an hour glass shape you would be losing black and gaining white down the sides. So the area of the white would be greater. Not a 50/50 even though the top distance is the same.



(3) If the black and white were not the same on top, but had an hour glass shape. You would be gaining and losing on top and gaining and losing down the sides. So you could theoretically have the same area of black and white, hence- a 50/50 without the top being the same.



Does any one agree or disagree with this thinking.
