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. What is the volume of a sphere (3-dimensional, not a hypersphere) [r = radius]?




2. Which of the following is an arctangent formula for pi?




3. 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?




4. Which of the following fractions most closely approximates pi?




5. The world pi-recitation record is held by Chao Lu of China. He was able to recite pi from memory to approximately how many decimal places?
