Because is is irrational, it cannot be expressed as a fraction. Because it is transcendental, it cannot be expressed as the root of a polynomial (like square roots can). In other words, without making up a symbol or a name specifically for pi, there is no simple way to express its exact value.
The reason the symbol was chosen is because pi is the greek version of the letter p. Like "p", pi is the first letter of the greek word for "perimeter". A circumference can be thought of as the "perimeter" of a circle, so the letter pi was chosen.

What is the equation pi?
"Pi" is not an equation - it is a constant. Pi is irrational, that is, it cannot be expressed as a ratio of constants, but it can be truncated for common use (approximately 3.1415). Pi is given by the circumference of a circle divided by the circle's diameter: Pi = C / d
What is a coeffiecnt in algerbra?
A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. A coefficient must be a number or a symbol for a constant number. This includes pi and e as coefficients.2x=6(pi)x=44(x+2)=19
What englishman introduced the pi symbol and in what year?
what Englishman introduced the pi symbol, and in what year
Is the symbol for Pi a Roman Numeral?

What does pi r equal?
pi is the constant value that was given by ARYABHATTA was 3.141 and here "r" is nothing but radius
Is the symbol pi considered a variable in math?
No. It is a constant. A variable is something that changes value in certain circumstances; pi always has the same value.
Does anyone really no what pi represents?
Yes, many people know what it represents; pi is the Greek symbol for the "circular constant", the ratio between the circumference and the diameter, which can be used to find the perimeters, areas, volumes and surface areas of many shapes given one or two particular measurements.
What is the constant number in a equation?
A constant is a number that does not change. It could be a regular number like "3" or it could be a symbol like "pi". If you were trying to find the circumference of a circle for instance, (C=2*pi*r) pi and 2 would both be a constant and r would be a variable (the equation is still true if you had a differently sized circle).
