Answer:
**Pi has been memorized to more than 120,000 digits**

In October, 2006, Akira Haraguchi set a new world record, reciting Pi to 100,000 decimal places. It is true that the Bablyonians were the first known estimators of Pi, using the value 25 over 8. The 32nd decimal of Pi is zero and it is not seen before this. And yes, the Bible does have a crude Pi calculation, I Kings 7,23: And he made a molten sea, ten cubits from one brim to the other: it was round all about, and his height was five cubits: and a line of thirty cubits did compass it about.

This values Pi as 3.

There is also reference to King Solomon's brass bowl, which gives a ratio of circumference to diameter.
