Why is March 14 celebrated as Pi Day?
A It represents the first three digits of pi
B It’s Albert Einstein’s birthday
C It’s the day pi was discovered
Pi, the ratio of a circle’s circumference to its diameter, is an irrational number represented by the symbol π. It has an approximate value of 3.14, which is why March 14, or 3/14, is Pi Day. In fact, after the decimal place, Pi’s digits continue indefinitely without repetition or pattern, making it impossible to pin down its precise value. March 14 also happens to be Albert Einstein’s birthday, but that is just a coincidence.
Correct Answer: It represents the first three digits of pi
