Urban myth.

From the Kings James Bible
1 Kings 7:23 
And he made a molten sea, ten cubits from the 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 round about.

There seem to be various explanations for the above but perhaps it is the genesis of the common “define the value of pi to be 3” idea?
