Answer explanation

An Old Testament passage describing a cylindrical vessel built for the Temple says,

"He made the cast metal basin, 15 feet from brim to brim, perfectly round. It was 7 1/2 feet high and 45 feet in circumference." -- 1 Kings 7:23 (CSB)

The measurements 45 feet (circumference) divided by 15 feet (diameter) give a rough approximation of pi.
