Yes, the digits of Pi are an infinite set. No, it is not possible to list the members of an infinite set.
Pi (π) belongs to several number sets, including the set of real numbers and the set of irrational numbers. As an irrational number, it cannot be expressed as a fraction of two integers, and its decimal representation is non-repeating and non-terminating. Additionally, since pi is a real number, it is also part of the set of complex numbers.
Pi is not a natural number. Natural numbers are just the regular set of numbers used for counting (1, 2, 3, 4, ...). Pi, being not even a whole number, is not natural.
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.
No; here's a counterexample to show that the set of irrational numbers is NOT closed under subtraction: pi - pi = 0. pi is an irrational number. If you subtract it from itself, you get zero, which is a rational number. Closure would require that the difference(answer) be an irrational number as well, which it isn't. Therefore the set of irrational numbers is NOT closed under subtraction.

Irrational numbers, since the value will be a multiple of pi.
It is {sqrt(2), sqrt(3.7), pi, and e}.
Any set that contains it. For example, the set {1, 2.3, 2.236067977} or {-79000, pi, 2.236067977, sin(47)} or all real numbers, etc
They are members of the infinite set of numbers of the form (2*pi)*k where k is an integer. Since the set is infinite, it is not possible to list them. Provided k is non-zero, these are all irrational (transcendental) numbers.
