 ## The Pi Trivia Game

Home : Pi : The Pi Trivia Game

 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. 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? 2 million 39 11 48,000 300 2. How does one convert pi in base 10 to base 2? Keep only the '0' and the '1' in the decimal expansion. It is impossible because pi > 2. Replace each digit of pi in base 10 with a 0 if it is divisible by 2 and with and 1 if it is not. Successively multiply pi by 2 and put a '1' when it is greater than 1 and a '0' when it is smaller than 1. Repeat this step after having kept only the fractional part of the result. Divide pi in base 10 by 5. 3. 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? the laws of reflection and refraction general relativity exploding pop-tarts the photoelectric effect the uncertainty principle in quantum mechanics 4. In 1897 a state House of Representatives unanimously passed a bill setting pi equal to 16/(sqrt 3), which approximately equals 9.2376. In which state of the United States did this occur? California Indiana Massachusetts Florida Canada 5. Which of the following is NOT equal to pi? 4 * the integral from 0 to 1 of sqrt(1 - x^2)dx 4 * arctan 1 the ratio of any circle's circumference to its diameter (3/4) * the number of radians in a 270 degree angle 2 * the number of radians in a right angle
