Pi (symbol π ) is a mathematical constant whose value is the ratio of any circle's circumference to its diameter in Euclidean space; this is the same value as the ratio of a circle's area to the square of its radius. (Area of a circle = πr2)
This number is the same for every circle. This means that for any circle, the length of the circumference divided by the length of the diameter equals pi. It's expressed in the formula pi = C/d , usually written as C = pi x d , finding the circumference when the diameter is known. The concept has been handed down for thousands of years, and it developed alongside mathematics for much of that time.
The exact value of pi can never be expressed exactly in numerical form. This is because pi is a transcendental number; it is irrational. But here are its first few digits (for more digits, see the discussion page):
Because pi is a non-repeating, non-terminating number, it is often approximated as 22/7, or 3.14, or 3.1416 in order to make calculations a little more manageable. As a fraction, its closest approximations for basic mathematical purposes are 22/7, 333/106 or 355/113.
As a decimal figure, 3.14 or 3.14159 are most generally used.
Pi is the ratio of the circumference of a circle to its diameter.
π is an irrational number, which means that its value cannot be expressed exactly as a fraction, Consequently, its decimal representation never ends or repeats.Other properties of pi
Pi isn't just about circles. It's not even just about geometric shapes. For instance:
* pi/4 = 1/1 - 1/3 + 1/5 - 1/7 + 1/9 - ...
* pi^2/6 = 1/1 + 1/4 + 1/9 + 1/16 + ... (the denominators are the square numbers)
* Pi appears in complex analysis, in a formula which expresses the nth derivative of a function as an integral.
* It also appears in Fourier analysis - the mathematical theory which allows us to, for instance, take a sound wave and calculate how much of it is at each frequency.
* In probability theory, the probability density function for the (normalized) normal distribution is exp(-x^2/2)/sqrt(2*pi).

The mathematical term of pi is approximated equal to 22/7. :)
The famous mathematical problems featuring pi include finding the area and the circumference of a circle. The value for pi is 3.14.
Pi as a mathematical symbol was introduced by William Jones in 1706
Pi is approximately equal to 3.141592652389793238462.
It is a decimal
Pi is a single number so there cannot be famous numbersof pi.
it is a mathematical number 3.1415926535897932362643433
pi, in the mathematical term.
Pi was first used as a mathematical symbol by the mathematician William Jones in 1706.
Pi is a mathematical term relating to circles, and there is no possible way to eat it.
Yes and it is for any circle: circumference/diameter = pi
Pi is a mathematical constant because it is the same for every perfect Circle. Pi = Circumference/Diameter of any Circle. It is constant because no matter the size of the circle that ratio always comes out to Pi. Hope they helped :)
pi is equal to 3.141592653589793238462643383279502884197169399375105...., pi is actually a endless mathematical ratio. pi is sometimes approximated by 22 over 7.
What is the value of pi.

Pi, the mathematical constant, has been around since circa 1706.
Ratio of the perimeter of a circle (circumference) to its diameter
Pi with a capital P and small i is a mathematical term. Pie is a dessert, such as apple pie.
