Yes, the digits of Pi are an infinite set. No, it is not possible to list the members of an infinite set.
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.
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.
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.
It is {sqrt(2), sqrt(3.7), pi, and e}.
Irrational numbers, since the value will be a multiple of pi.
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.
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
there are infinite numbers in pi
To any set that contains it!It belongs to {-4.5},or {-4.5, sqrt(2), pi, -3/7},or multiples of -0.5,or negative numbers,or rational numbers,or real numbers,or complex numbers,or square roots of 22.25,etc.To any set that contains it!It belongs to {-4.5},or {-4.5, sqrt(2), pi, -3/7},or multiples of -0.5,or negative numbers,or rational numbers,or real numbers,or complex numbers,or square roots of 22.25,etc.To any set that contains it!It belongs to {-4.5},or {-4.5, sqrt(2), pi, -3/7},or multiples of -0.5,or negative numbers,or rational numbers,or real numbers,or complex numbers,or square roots of 22.25,etc.To any set that contains it!It belongs to {-4.5},or {-4.5, sqrt(2), pi, -3/7},or multiples of -0.5,or negative numbers,or rational numbers,or real numbers,or complex numbers,or square roots of 22.25,etc.
It belongs to any set that contains it! For example, {-1.576}, or {45, sqrt(2), pi, -3/7, -1.576}, or numbers between -43 and 53, or rational numbers, or real numbers, or negative rational numbers, etc One set in particular that includes -1.576 is the set of rational numbers (ℚ).
You would find it in any set that contains it! For example,the set of negative integers.the set of all rational numbers.the set of real numbers smaller than -55.the set {pi, 37.62, -59, sqrt(19.7)}
