If you have a circle ... any circle ... and you measure its circumference, measure its diameter,
and divide the circumference by the diameter, the answer is always the same number, which
people have decided to label with the name "pi".
"Pi" is the ratio of a circle's circumference to its diameter, but "pi" is not a rational number,
since it's not the ratio of any two integers.

Why is pi a constant?
Pi is a constant because it is the ratio of the circumference to the diameter of a circle and they are always in the exact same proportion.
Where did pi start?
The observation that the ratio of circumference and radius is constant.
Are pi's digits peridic?
The digits of pi are not periodic. Pi is an irrational constant, and if its digits were periodic, it could be expressed as a ratio of constant integers, meaning it would be rational.
What number comes before pi?
The number that comes before pi is 3.14159265358979323846... which is the mathematical constant representing the ratio of a circle's circumference to its diameter. Pi is an irrational number, meaning it cannot be expressed as a simple fraction, and it is approximately equal to 3.14159. Therefore, the number before pi is 3.
Is the ratio of the circumference to the diameter is constant for any circles?
Yes, pi.
Why is pi a mathematical constant?
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 :)
Can you explain pi?
The number π is a mathematical constant that is the ratio of a circle's circumference to its diameter. The constant, sometimes written pi, is approximately equal to 3.14159. It has been represented by the Greek letter "π" since the mid-18th century.

Why is pi 3.14 and not other numbers?
The ratio of the circumference of a circle to its diameter is a constant, irrespective of the actual measurements. This ratio is called pi and is 3.1415...
Why does pi not have units?
Pi is a natural constant of the ratio circumference divided by diameter. That ratio cannot have any unit.

Is the ratio of the circumference to the diameter is constant for any circles?
Yes, pi.
Pi is a mathematical constant related to circle define Pi?
Ratio of the perimeter of a circle (circumference) to its diameter
What is the heck is pi and who invented it?
pi is a transcendental number which represents the constant ratio between the circumference of a circle and its diameter. It is a universal constant and nobody invented it.
Did Leonhard Euler made pi?
NO! Of course he didn't make pi. Pi is a constant that describes the ratio between the circumference and diameter of a circle. So he can not have made pi as it is a constant. Also, he didn't discover pi either, the earliest use of this constant is by the egyptians upon building the great pyramid at Giza in which 2*pi was used as the ratio between the height and perimeter of the pyramid. So basically, no.
