Finally this is your chance to pay tribute to the magnificent transcendental number that we have all grown to love! Test your knowledge of history, mathematics, and even a little physics.

Here are 25 (given to you 5 at a time) fun pi-related questions, picked randomly from my exciting pi question database! Get ready for the thrill of your lifetime, the ultimate challenge, The Pi Trivia Game!

Pi Flower
1. Which of the following binary numbers is closest in value to pi:
11.0010010000111111
101.110101000111100
10.0001101010110100

111.010111101011111

2. 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

3. 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

4. What 1768 proof about pi is the German mathematician Johann Lambert famous for?
Pi > e.
No pattern exists in pi's digits.
Pi is irrational.
The area of a circle is equal to pi times the square of its radius.
It's fun to recite digits of pi.

5. 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
