Answer 4

Pi or π is a mathematical constant which represents the ratio of any circle's circumference to its diameter in Euclidean geometry, which is the same as the ratio of a circle's area to the square of its radius. It is approximately equal to 3.14159. Pi is one of the most important mathematical constants: many formulae from mathematics, science, and engineering involve π.

Answer 5

Pi is the ratio of a circles circumference to its diameter.

National Pi Day is March 14th (3.14), March 14th is also Albert Einstein's birthday!

Pi is irrational.

Pi is transcendental.

Pi in Binary looks like this: 11. 00100100 00111111 01101010 10001000 10000101 10100011 00001000 11010011 00010011 00011001 10001010 00101110 00000011 01110000 01110011 01000100 10100100 00001001 00111000 00100010 00101001 10011111 00110001 11010000 00001000 00101110 11111010 10011000 11101100 01001110 01101100 10001001  

For anyone that has ever touched any form of trigonometry, geometry, or calculus - the significance of pi becomes very clear, both in the ideal cartesian plane, and in the natural world. From a drop of water, to the planets and the stars, pi is a necessary constant in determining the circumference, area, or volume of any spherical or circular object - all that is needed is the diameter. However, pi is irrational, it's preciseness will never be fully uncovered.

Fortunately, many people have spent countless hours formulating more digits of pi than will ever be necessary!  

Formulating pi can be done in a variety of procedures, the arctangent method is one of the oldest.

It follows that arctan 1 (radian) * 4 = pi

Other methods such as the Ramanujan and the Guass-Legendre are used to gather more correct decimals per iteration of the respective formula.  

You want some pi?

More than You'll ever need:

51 digits of pi   [and why]

10 Million Decimals of pi

1 of 10     [first 1 million digits]

2 3 4 5 6 7 8 9 10     [respective blocks]

200 Million Decimals of pi

1 of 20     [first 10 million]

2 3 4 5 6 7 8 9 10 11 12

13 14 15 16 17 18 19 20  

The first 51 digits of pi

The important ones. For all practical purposes no more than 10 digits of pi are required for mathematic computation, however even with astronomically precise calculations no more than fifty are really necessary. Why is 51 so significant you might wonder, well it's not. The truth is that pi is easier to memerize in blocks - blocks of 10 are nice since that follows our counting system. To stay aesthetically pleasing, it makes more sense to write out 5 blocks of 10 of the respective digits. With the initial value of 3, that adds up to 51.

3 .   1 4 1 5 9 2 6 5 3 5

8 9 7 9 3 2 3 8 4 6     2 6 4 3 3 8 3 2 7 9

5 0 2 8 8 4 1 9 7 1     6 9 3 9 9 3 7 5 1 0

That's it. That is all that is needed out of pi. If you memorize just those few digits, you will possess information accurate to near perfection, no wordly example will ever create circularity as precise as those 51 digits will allow.
