It's a pity that we have no facepalm smiley.

I was only implying that you took soroban's post, meant in a humorous way, and interpreted it as if it was in all seriousness. So, no need to stop trying to help. I meant no offense, I just thought you missed soroban's intent entirely.

Thus a circle had no sides.

It is!

In any case, there is fun mathematics to be had by taking the area of a regular polygon in terms of the number of sides and the 'radius' and using L'Hopital's rule to determine what the area should be as $\displaystyle n \rightarrow \infty$. I started typing it out but I'm at work and it's not my lunch break yet!
