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. What is the earliest known reference to pi?




3. Which French mathematician said in 1909 that it is hopeless to think that we could ever check if there are 10^100 consecutive zeroes in the decimal expansion of pi?




4. If one were to find the circumference of a circle the size of the known universe, requiring that the circumference be accurate to within the radius of one proton, how many decimal places of pi would need to be used?




5. For many years, it has been conjectured but unproven that pi is normal in base 10. What does normal mean?
