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. There was a time (a while ago) when people were trying very hard to 'square the circle.' It was said at the time that it was even an illness and a name was given to it. What is it?

Squarerootofpitis
Impossibilus Fittis
Morbus Cyclometricus
WileECoyotisandRoadRunneritis
Repetitionatis Decimalus

2. Are pi's digits periodic?

Yes; the digits repeat themselves after every 6000 decimal places.
No; only women, not numbers, are unfortunate enough to be periodic.
Maybe; not enough digits of pi have yet been calculated to know if they start eventually repeating themselves.
Yes; every infinitely long number has to start repeating itself sometime.
No; every periodic number is rational, but pi is irrational.

3. In 1949, a digital computer was first used to calculate pi. To how many decimal places was this computer, ENIAC (Electronic Numerical Intergrator and Computer), able to find pi (it took 70 hours)?

10,493
576
2037
8331
297,454

4. Say you have a rope wrapped tightly around the earth at the equator. How much longer would you have to make the rope if you wanted the rope to be exactly 1 foot above the surface the whole way around? (assume that the earth has a constant radius at the equator)

2*pi feet
2*pi*R feet, where R is the radius of the earth
pi*R^2 feet
pi + D feet, where D is the diameter of the earth
pi/2 feet

5. 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
