This is the value of pi that we are talking about. There really is no point in talking about the uncertainties of a physically drawn circle in terms of a theoretical ratio. If it helps you understand the theoretical nature of $\pi$ we have several varieties of equations to choose from that aren't physical but produce the same answers. Here's one of my favorites: $\frac{\pi ^2}{6}= \sum _{n = 1}^{\infty} \frac{1}{n^2}$ This can be shown to be the same $\pi$ as we find in a circle. -Dan

No, $\pi$ = 3.14159265... (continuing indefinitely).
