> **Reopened**

Request for reopening: https://math.stackexchange.com/questions/730117/what-would-change-in-mathematics-if-we-knew-pie-is-rational  

It was closed as unclear last March.  I edited it to try to make it clear, and there are comments that (to me) show that the question can be answered reasonably.  I voted to reopen, then it went through review and left with 3 selecting "leave closed."
