Does The Bible Say Pi = 3?

Nope.  The relevant passage is 1 Kings 7:23 which says "And he (Hiram) 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." Critics love to point out that if it was ten cubits across, and thirty cubits around, then this would mean that pi equals three, when it actually equals about 3.14.

First of all, the circumference equally exactly pi times the diameter is only true of perfect circles (which only exist in theory).  Try making a circular object yourself, and you'll find that the circumference will only be roughly pi times the diameter.  It may be 3 times as great.  It may be 3.3 times as great.  Especially if you make the object without using any more measuring tools than Hiram used (his measuring tool was likely his forearm, since that is how cubits were measured).

Also, pi equalling 3.14 itself is an approximation, as is 3.  Why is 3.14 an appropriate approximation, while 3 itself is not?  No one has ever written, or even calculated, the exact number for pi, since there is no exact number (it would be eternal).  Three is correct within 95% of the actual value, while 3.14 is correct within 99.9% of the actual value.  So who decides what kind of rounding off is close enough?  Do the critics really expect this passage to end with, "....and a line of 31.4159265 (etc, etc.) cubits did compass it round about"?

Everyone approximates.  When a financial report says a company is worth 10 billion dollars, do people complain that the company is actually worth $9,824,023,855.03?  Even those pointing out the 'error' here are approximating in whatever value they express for pi.  There are many examples in the Bible of obvious approximations.  For example, the populations given in Numbers Chapter 2 always end with even hundreds, or in some cases fifties.  Are we expected to believe that each population came out to such exact numbers?  Nope, that is yet another example of approximations in the Bible.

Approximation is not considered an error, so there is no error in this passage.

Look at verse 26

Three verses later it says, "its rim was like the rim of a cup, like a lily blossom." In other words, it flared out at the top. It may be that the diameter measurement included the flared lip, but the "line ... around it" did not, since it would be much easier to measure the circumference just below the flared rim rather than on its edge. Doing the calculations show that, if this interpretation is correct, the lip would flare out almost exactly 4 inches, a value that is easy to believe given a 15-foot diameter.Posted by BorderlineADD on May 18, 2012
