Holy fuck /sci/ is garbage.
>>11730119This does not answer OP:s question. It just states that pi is the ratio of circumference to diameter, but does NOT show that this ratio is constant, and that pi is therefore well-defined.
>>11730137Again, you're using what you're supposed to show: C/D = pi.
>>11730153I won't even dignify this with a proper response.
>>11730188>wildburgerHere's a simple proof. Take any two circles with radii and . A translation followed by a dilation of shows that these two circles are similar, i.e. , or in other words .
