c/πd
[/quote]

c/πd equals 1, and as such it is not a rational fraction that gives you pi, as they were discussing. Pro tip: if pi is in the fraction it's not rational and it probably won't equal pi.

c = πd
thus
c/πd = πd/πd = 1

Then you're probably not as much of a math genius as you thought. This is intro to geometry level content here. :hehe
