## circumference and width.

Hi,

i been considering the problem of width of a circle which is it’s diameter and the circumference, especially if you squash the circle flat.

Zumba bangle

the width is the diameter, any straight line thru the centre of the circle, it is the width times pi that gives the circumference. if you squash the bangle flat, it would be half the circumference. so a circle that is 1 unit in diameter would be 3.14 circumference and it would be 1.57 if layed flat.

here is a list of numbers that may not make sense but I like ’em:

 width diameter circumf flat width 1 3.14 1.57 10 31.40 15.70 42 131.88 65.94 44 138.16 69.08 46 144.44 72.22 48 150.72 75.36 50 157.00 78.50 52 163.28 81.64 54 169.56 84.78 56 175.84 87.92 58 182.12 91.06 61 191.54 95.77 69 216.66 108.33 76 238.64 119.32 flat width circumf diameter 1 2 0.64 10 20 6.37 42 84 26.75 44 88 28.03 46 92 29.30 48 96 30.57 50 100 31.85 52 104 33.12 54 108 34.39 56 112 35.67 58 116 36.94 61 122 38.85 69 138 43.95 76 152 48.41

interesting what the difference is, dontcha think? though the 2nd table is closer they are still a bit out. So if one was using the ‘width’ as the squashed flat bangle distance then the diff could be the thickness of the bangle. The top down width, ie how wide a circle looks top is quite different in the last column.

mmm, makes my brain boil.
