    Well, with those numbers, it’s easy math. :)

    V=5*10^2*10

    5,000. 5,000 what though?

    Even with a proper π value, it still doesn’t make sense… 3,141.59265359

      What? Its just the volume, without units. What part of it doesn’t make sense?

        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.

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

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

          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.
