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. Pi is ubiquitous in the branch of mathematics known as statistics. The maximum height of what famous curve is equal to 1/sqrt(2*pi)?




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




3. The new world record for computation of the most digits of pi was achieved in September/October 1995 by Yasumasa Kanada at the University of Tokyo. It took 116 hours for how many digits to be computed?




4. Consider the following series of natural numbers, constructed by taking successively larger strings of digits from the beginning of the decimal expansion of the number pi:
3, 31, 314, 3141, 31415, 314159, 3141592, etc.
Out of the first 1000 numbers in this series, how many are primes? (for example, the first two numbers, 3 and 31, are both primes)




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?
