Answers
This is the symbol
known as " PI ".
_________________
We know an formulae,
" Circumference = 2 × pi × radius "
Now , 2 × radius = diameter.
Thus, Circumference = pi × diameter
Or, pi = Circumference / diameter
Or, pi = Circumference : diameter .
_________________
So, " PI " can be defined as the ratio of the Circumference of a circle to its diameter.
________________
The general value of " PI " is
= 22/7
= 3.14159....
Note : Pi an irrational number so, we cannot say its exact value.
________________
" Pi " is an Greek letter which now-a-days is used in various numericals of physics and maths.

Here's a brief history of finding π.
The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi π
The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
