Its the circumference of any circle divided by its diameter.

"now if we were to cut the corners of the box in such a fashion as they would cut in and touch the circle, the perimeter does not change and is equal to 4. " This statement is not true. Proof: There is a triangle being cut away from each corner of the original box. This is a right angle triangle where the two sides that were originally part of the outer square s perimeter are now being replaced by the hypotenuse of the triangle. For ANY triangle, the sum of the lengths of the two shorter sides will ALWAYS be greater than the length of the longest side. Therefore the new perimeter after cutting away the corners will be less than 4. Specifically, in the case of replacing the square with an octagon by cutting away the four corners, the original perimeter is 4, and the new perimeter is 8/(1+2^1/2) or 3.3137.... As the corners are cut off, each removed corner is a triangle with two old sides replaced with one new side, the single side always being shorter than the sum of the initial two. As the process continues, the perimeter reduces until when there are infinite sides (and therefore no remaining corners) the length of the perimeter is 3.14159...

Pi is the number to calculate the circumference of any circle. It is expressed as C=Pi x R(squared). The number is a non-repeating number that is infinite. (it has no end). The circumference is 3.14 times the square of the radius of the circle. I know this sounds useless but get all the math you can. It will help you throughout your life.

Pi (π) is an irrational number... its pretty much never ending. It is commonly simplified to 3.14.
It is the ratio of a circle's circumference (length around the circle) to its diameter (length across the circle through the center), and is used to calculate the circumference, area, and others.
Area of a circle = π times radius squared
Circumfererence = π times diameter

Pi is the constant quantity which the diameter of a circle needs to be multiplied by to calculate the circumference. It is a very important quantity in many mathematical calculations throughout history. I am not sure why you are asking this in the "Medicine" category though.

It is impossible to state Pi completely accurately, it is the ratio of the circumference of a circle to its diameter. It is roughly 3.14159265359... but you can always calculate it more accurately than you can write it.
The web site below lists Pi to 1 million places, but people have calculated it to tens of millions of places.

Pi is a never-ending, never-repeating decimal. It is the circumference of a circle divided by its diameter. It is equal to 3.14159265358979323846264338327950288419716939937510....

pi is 3.14159... it goes on forever and doesnt stop. it originates from the the 5 (i think) letter in the greek alphabet and is used for formulas about circumference and area of a circle.

Pi is 3.14159....
It is a constant used in many math equations that involve circles, like circumfrance, area, volume of sheres, etc.
