which of the following desribe pi select all that apply real number natural number rational number irrational number

Answer 1

The number π (pi) can be described as follows:

1. Real number: True. π is a real number because it exists on the number line.

2. Natural number: False. π is not a natural number, as natural numbers are positive integers (1, 2, 3, ...), and π is approximately 3.14159, which is not an integer.

3. Rational number: False. π is not a rational number because it cannot be expressed as a fraction of two integers.

4. Irrational number: True. π is an irrational number, meaning it cannot be expressed as a ratio of two integers, and its decimal representation is non-repeating and non-terminating.

So, the correct descriptions of π are: real number and irrational number.
