Math the king of the sciences , without math our lives couldn't be like we know them .
Without math the school wouldn't have that thrill you like , you like math don't you .
Yet, math is a dare that everybody should acomplish ,even if we don't want to .
In this Instructable i will tell you the 2 most common methods to obtain the area of any circle .

You'll need a small number of implements to determine the area of a circle :
Here's a small paragraph about the numerical value of pi (Thx a lot wikipedia!)
The numerical value of pi truncated to 50 decimal places is:[11]
3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510
See the links below and those at sequence A000796 in OEIS for more digits.
While the value of pi has been computed to more than a trillion (1012) digits,[12] elementary applications, such as calculating the circumference of a circle, will rarely require more than a dozen decimal places. For example, a value truncated to 11 decimal places is accurate enough to calculate the circumference of the earth with a precision of a millimeter, and one truncated to 39 decimal places is sufficient to compute the circumference of any circle that fits in the observable universe to a precision comparable to the size of a hydrogen atom.
Because pi is an irrational number, its decimal expansion never ends and does not repeat. This infinite sequence of digits has fascinated mathematicians and laymen alike, and much effort over the last few centuries has been put into computing more digits and investigating the number's properties.[15] Despite much analytical work, and supercomputer calculations that have determined over 1 trillion digits of pi, no simple pattern in the digits has ever been found.[16] Digits of pi are available on many web pages, and there is software for calculating pi to billions of digits on any personal computer.

Don't worry we will be using a truncated 5 digit value : 3.1416
We'll get a (mostly) accurate number with this value
- First you need to know the basic value of pi
