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

2. Who, in 1706, first gave the Greek letter "pi" its current mathematical definition?

3. What is the volume of a sphere (3-dimensional, not a hypersphere) [r = radius]?

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. 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?
