You can see this on the surface of the Earth
Yes, except that conventionally pi is a constant, so you should be saying that the ratio of tyhe circumference to diameter becomes less than pi. Just a small nit picked. Just about all of modern maths goes out the window if pi changes value, as nearly happened in Indiana (http://en.wikipedia.org/wiki/Indiana_Pi_Bill) Actually, that is a rather instructive example of crackpottery!
