Thanks Lennon - as I said 6.283 m give or take a few decimal points
.
Everyone who trusts in the geometry will come to that answer very quickly, but then a surprisingly large amount of people will probably then dismiss the answer of a little over 6 metres as being impossibly small. I mean to say - to shift the radious a full metre over the circumference of the world? I ask you
.
Variol - you stopped short of letting something = x (or d or r or whatever) and so stopped short of realising that a solution was available now rather needing to know the diameter.
For those who struggle to place their faith in maths, it's only when you look at the infintismally small difference in percentage terms that a metre makes on the diameter of the erath that you rationalise that it takes very little rope to make this change.
