Finally this is your chance to pay tribute to the magnificent transcendental number that we have all grown to love! Here are 25 questions (given to you 5 at a time), picked randomly from my pi question database. Get ready for the thrill of your lifetime, the ultimate challenge, The Pi Trivia Game!

1. Which of the following is NOT equal to pi?




2. Answer the following question (an example of pi's importance in probability), posed and solved by George Louis Leclerc, Comte de Buffon (solved also nowdays by many students in introductory statistics classes): Let a needle of length L be thrown at random onto a horizontal plane ruled with parallel lines spaced by a distance d (greater than L) from each other. What is the probability that the needle will intersect one of these lines?




3. If you were writing a computer program with the intention of breaking the world record for calculating the most digits of pi, why would it be foolish for you to use the well-known formula pi/4 = 1 - 1/3 + 1/5 - 1/7 + ...?




4. The physicist Willebrord Snellius (1580-1626) found polygons which better approximated the perimeter of circles than do inscribed and circumscribed polygons. Better perimeter approximations lead to more quickly converging pi approximations. What scientific discovery is Snellius best known for?




5. Who, in 1882, proved the transcendence of pi?
