The circumference of any circle divided by its diameter is always equal to pi which is about 3.142 rounded to 3 decimal places.
The exact true value of pi is not known because the decimal places of pi are infinite.
To calculate properties of circles
Usually a circle but its properties can also be applied to spheres
They have a circumference which is 2*pi*radius or diameter*pi They have an area which is pi*radius2 They have sectors They have chords They have segments They have a total of 360 degrees around their circumferences They have arcs which is part of their circumferences They can have a tangent which is a straight line that touches it at one point
A ball with that many faces would be close to a sphere, so its volume ans surface area, and other properties could be approximated using pi.
They are measures of angular displacement. In two dimensional space they may be measured in degrees (by beginners) or in radians. There are 2*pi radians in a revolution. In 3-d space angles are measured in steradians. A sphere measures 4*pi steradians

Circumference C of a circle divided by diameter d of the same circle = pi. Pi is irrational because the properties. Pi = 3.14159 26535 89793 23846 26433 83279 50288 41971 69399 37510 ...

Many properties. For example, 1 + 1/1! + 1/2! + 1/3! + 1/4! + ... = e. This is not true for pi.
A pi-acceptor is a molecule that can accept electrons from another molecule's pi bond. This interaction helps stabilize the overall structure of the molecules involved, influencing their chemical properties and reactivity.
Pi donor ligands are molecules that can donate electron density to a metal center through their pi orbitals. These ligands typically have unsaturated bonds, such as double or triple bonds, which allow them to form strong coordination bonds with metal ions. Pi donor ligands are often planar and can be aromatic or non-aromatic. They are known for their ability to stabilize metal complexes and influence their reactivity and properties.

The simple answer is that PI is what falls out when you study circles. If I had a circle that is 1 foot in diameter, then the circumference (or perimeter) is PI feet. The numerical value of PI wasn't chosen at random, it was found. As for the area of a circle, the perimeter of any object has a relationship to its area. So, PI again becomes important.
A ball with that many faces would be close to a sphere, so its volume ans surface area, and other properties could be approximated using pi.
Pi donor and pi acceptor ligands play a crucial role in coordination chemistry by donating or accepting electron density through their pi orbitals. Pi donor ligands, such as phosphines and alkyls, donate electron density to the metal center, while pi acceptor ligands, such as carbon monoxide and cyanide, accept electron density from the metal center. This interaction helps stabilize the metal complex and influences its reactivity and properties.
The constant "pi" 0,314159...... is used in every branch of science, from calculating material quantity for domes in construction to calculating absorption properties of new substances in chemistry. To calculate the circumference of a circle = c = 2(pi)r The area of a circle a = (pi)r² you can also use the formula (pi)d to find the circumference Although pi has solved countless problems, no problem has ever been solved with whatever pi equals EXACTLY. Therefore, when using pi to solve a problem, the majority of mathematicians and scientists round pi down to 3.14
