Yes, 2π is a real number.
Here's why:
-
Real Numbers: Real numbers encompass all rational (e.g., 2, -3, 1/2) and irrational numbers (e.g., √2, π).
-
Pi (π): Pi is an irrational number, approximately equal to 3.14159. It is a real number.
-
Multiplication: When you multiply a real number (2) by another real number (π), the result is also a real number.
-
2π as a Real Number: Therefore, 2π is a real number. Because π is irrational, multiplying it by 2 still results in an irrational number, which is a subset of real numbers. 2π ≈ 6.28318530718.
In short, 2π belongs to the set of real numbers.
