Second, we should consider the matter of significant figures. On a physics test, if a circle is said to have a diameter of 10 feet and the student is asked to compute the circumference, the correct answer is 30 feet—*not* 31 feet. The reason 31 feet is an incorrect answer is because it implies a precision that is unwarranted by the given information. The value *10 feet* indicates that the diameter has been rounded. Perhaps it has been rounded up from the exact value of 9.5 feet, in which case the exact circumference would be 29.845. . . feet—which rounds up to 30 feet.

This is such a desperate stretch that I can't believe even Answers in Genesis would offer it as a serious explanation. Sometimes I wonder if the apologetics there actually believe their own explanations.

No physics or geometry test worth its salt would reject 31 as an incorrect answer, certainly not because of some precision the test-taker is supposed to infer. The worst part is AIC says 30 is the correct answer and 31 is incorrect because "perhaps it has been rounded up from the exact value of 9.5 feet." Well guess what? It could just as easily have been rounded *down *from the exact value of 10.49 feet,* in which case 33 feet would be the correct answer*. There is no way to know from the question. Saying 30 is correct and not 31 because "perhaps it was rounded up" is laughable.

When biblical inerrancy is your axiom, it's amazing the mental gymnastics you must perform.
