March 14 is National Pi
Day, celebrating the measurement of the ratio of the circumference
of a circle to its diameter.
Pi is actually an endless number that some diehard fans have
calculated to over a trillion decimal places. We've shortened
that a bit, to a mere 20:
3.14159265358979323846
Ready for some pi? Each answer. Each answer appears below
after the deciimal point. Answers are
anywhere from one to four consecutive digits long.
Fill in the blanks below and then tell us you're ready for pi. We'll
respond by showing you how many answers you have correct.
What we won't tell you is which answers are right and which are
wrong. You'll just have to keep trying until you get them all
correct.
