The volume of a cylinder is found using the formula V = πr2h. Using π = 5, r = 10 and h = 10. Find the volume V.

      Considering that the r and h are 10, you could still easily do it without calculator, even if the value of pi had plenty of decimals.

        Yeah it’s not hard, but if the instructor just wants to test if you can follow directions and plug extremely simple numbers into an equation without a calculator then this is fine. I’d almost expect this on a test for some trade skill, like some 1-2 year certification you know?

        it could still =3 tho

    Pi is a geometric constant, so obviously we’re redefining the decimal numbering system to make “1” anchored to a fixed value of π/5 (or simply 1 in our superior new decimal representation).

    Don’t believe the haters who’ll complain about “needing integer number representations”. Literally anyone with a basic grasp of fractions will be perfectly fine! Let’s illustrate with a few simple examples:

    • “I’ll take three-fifths pi gallons of blue slushie, please”
    • “No thanks, I don’t need any cups because I actually brought two-fifths pi containers of my own each with three-tenths pi gallons of individual capacity specifically for this purpose”.

    As you can see, there is no reason to be concerned whatsoever. The system works. It is mathematically elegant.

        Okay, I love the fact that we are so low on traffic currently that it makes perfect sense to reply to weeks old messages, and I am going to work on my inhibitions along those lines.

          I like that about Lemmy, actually. On that other site, if you didn’t get a comment in within a few minutes, you usually got zero engagement.
