It is pi, a letter in the Greek alphabet, and pronounced like pie. This infinite value, usually expressed as 3.14 or sometimes more accurately as 3.1416 is the ratio of the diameter (distance across) a circle, and the circumference (distance around) a circle. The diameter times pi equals the circumference, and the circumference divided by pi gives the diameter. Also, the radius (half the diameter) times itself and then multiplied by pi gives the area inside a circle. The value of pi is the same regardless of the size of a circle.
In relation to the area of a circle: pi*radius^2
A pie chart would show this. The full circle represents the whole, and each slice shows how big each part is in relation to the whole.

How big is the pie? Or, if you're speaking of pi, you have to know the size of the circle.
The value of pi for any circle is the circle's circumference divided by its diameter.
An arc is a part of the circumference of a circle.
The circumference of a circle divided by its diameter is equal to the value of pi.
By definition Pi is the relation between the radius and circumference of a circle.
In relation to the area of a circle: pi*radius^2
It is a sector of the circle
There is no direct relation between the area of a sector and the length of an arc. You must know the radius (or diameter) or the angle of the sector at the centre.
Yes, a circle graph and a pie chart are the same thing
Pie is a symbol that represents a number (3.14159...). Pie algebra is when the number Pie is used in algebra like the ccircumference of a circle. A circumference of a circle is worked out by Pie algebra: DxPie (diameter x Pie). Its a bit complicated to explain but...
A pie chart would show this. The full circle represents the whole, and each slice shows how big each part is in relation to the whole.
The area of a circle, in terms of pie, with a diameter of 36 is: about 324pi
It's a Pie graph or Pie Chart are two other common names for a circle graph.
