Pi [  ], 3.14159... - the ratio of the
circumference of a circle to its diameter - has puzzled mathematicians
for almost 4,000 years. We have never found an exact value for pi,
which has infinitely many numbers to the right of the decimal point.
Pi Day is often celebrated on March 14 in elementary schools in
the United States.
Elementary Problems of the Week in which pi plays an important part are listed below. For background information, read The Joy of Pi by David Blatner, or visit the Dr. Math FAQ about Pi. To find relevant sites on the Web, browse and search Pi in our Internet Mathematics Library; to find elementary sites, go to the bottom of the page, set the searcher for late elementary level (3-5), and press the Search button.
