    This is the correct answer. Pi is known. What it’s decimal expansion looks like is irrelevant. It’s 1 in base Pi.

      Yup, similar to the square root of two and Euler’s number.

      These are numbers defined by their properties and not their exact values. In fact, we have imaginary numbers that don’t have values and yet are still extremely useful because of their defined properties.
