Comment on Let π = 5

  Well, a r=10 and h=10 doesn’t mean much without units. 10 what? Feet? Meters? Inches? CM?

  Let’s take the OG numbers and assume feet, so 5,000 cubic feet. That’s not a useful volume measurement.

  1 cubic foot of water = 7.48052 gallons

  So 5,000 cubic feet of water = 37,402.6 gallons. That’s a viable volume measurement.

  1 cubic meter = 1,000 liters.

  5,000 cubic meters = 5,000,000 liters.

    Its not supposed to mean anything, it’s about the equation not about the end result. We’re not calculating an actual cilinder

      If we’re not calculating something useful, then why are we here and not in the library learing about the universe?

      Better question: What curvature of space is necessary for the apparent value of π to be 5?

        We’re learning maths, which is arguably the foundation of the universe.

        I’m afraid that that is beyond the comprehension of my human existence

        honestly I don’t know if there is any way to measure curvature of space , but its slightly more curved than the surface of a ball (where π=~4.712)

    The unit is unit.

    The math doesn’t care, and what you’re on about only really matters if the units don’t start as all the same or if you start converting between things.
