When discussing mathematics, it is important to show your work.
I have noted in the past couple of years of working with my son that the American school system fails to teach this basic truism.
So -- since you have not shown anything close to a bit of work (including providing neither the question or proposed answer),
one must presume that the mistakes are entirely yours.
@Bob - "Pi" is a Greek letter and Greek mathematical concept used in modern Greek-Arabic base-10 math.
The Bible is a collection of Hebrew books from ancient Israel which used Mesopotamian base-60 math.
That there's your problem.
As they say in computing "garbage in - garbage out"
@? - (to the follow-up on this) - did you read the Hebrew? How do you know the proper expression for the specific issue in that time period? - as mentioned below - you'll have to read the analysis by Vilna Gaon.
Lets make it simple -- 10th to 8th century BCE Israel had a many-hundred year industry of round, metal bowl manufacture. In fact, Israel was at the heart of the bronze trade in the period (look up the history of mining in the Negev, near present day Eilat).
If your analysis makes it unlikely that a bowl can be properly manufactured -- then your analysis misinterprets the source.
This is part of the basic rules for reading ancient documents.
Learned my math basics in the USSR - when it was still a stable world power producing the best in the engineering professions.
For anyone actualy interested, there is a book by the Vilna Gaon where some of the Biblical math is translated into modern math.
However, the Vilna Gaon wrote in Hebrew and I don't know if there is an English translation.
