The set of rational numbers is represented by Q.
The set of real numbers is represented by a fancy script "R". However, real numbers are just represented by a number (be it integer, rational, irrational, or otherwise). The key here is that it is not a complex number (number containing the imaginary number "i").
Pi (π) belongs to several sets of numbers, primarily the set of real numbers and the set of irrational numbers. As an irrational number, it cannot be expressed as a simple fraction, meaning its decimal representation is non-repeating and non-terminating. Additionally, since it can be found on the number line, it is also a member of the set of complex numbers, where it can be represented as π + 0i.

A Closed Circle means that that number is INCLUDED in the line of numbers. An OPEN circle means the line of numbers go up to the given number , BUT does NOT include the given number.

All real numbers.
number line
The set of whole numbers is represented by Z.
number line- a straight line on which there is indicated a one-to-one correspondence between points on the line and the set of real numbers. basically a line with numbers on it.
the set of real numbers
The set of all real numbers usually represented by a capital R that is double vertical line in the left and bold.

There is no representation for irrational numbers: they are represented as real numbers that are not rational. The set of real numbers is R and set of rational numbers is Q so that the set of irrational numbers is the complement if Q in R.
