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. 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?




2. What rapidly converging formula for calculation of pi was found by Machin in 1706?




3. At which decimal of pi does the earliest occurrence of the string 999999 begin?




4. One way to calculate the value of pi is to find the perimeter of polygons inscribing and circumscribing a circle. The circumference of the circle lies in between those two values, and the values approach pi as the number of sides of the polygon approaches infinity. Who originated this method of pi approximation?




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