Pi is now 5 due to inflation
Having Pi equal five definitely does not help the world go round.
To be Devil’s Advocate:
Given that the rest written in Comic Sans, it may be an early elementary school exercise, aimed at teaching kids to do multiplications. In this case, it’s tolerable and/or defensible to find a simplification for pi.
That said, making pi equal to 3 would have been more accurate for that…
Unless the kid is even slightly above average and finds the idea that pi equaling 5 confusing.
…if they’re above average, I think they’ll figure out the explicitly defined variable. I think the instructor is trying to make sure this problem doesn’t require a calculator and figured defining pi as 5 makes it clear that you can treat it as a whole number. 3 would be more accurate and just as easy, but meh idk that this is that great of a blunder.
You can be a smart kid and not realize that adults are lying.
I remember the Peas and the Punnett Square. Sure, mendelian genetics explains pea plant colors, but doesn’t explain dog fur colors. Just providing a footnote that more completed genetics exists would have been nice.

That’s a dumb way of teaching and you are a dumb devils advocate for saying it. Go to H E double hockey sticks.
Even in engineering it is common to just round pi to 3 and quickly estimate whatever it is your doing.
In astronomy, pi=1 or 10, depending on whether you’re trying to over or under estimate something. Because when you’re trying to estimate distances measured in millions of light years, the difference between 3 and 10 is just one or two orders of magnitude on a small number. It’s pretty common for astronomers to do napkin math by rounding every single number to the nearest zero. 91k becomes 100k for instance. Because the napkin math estimations are just trying to gauge whether some celestial event or object is a thousand light years away, ten thousand, a hundred thousand, etc… And pi becomes 10, because that’s the nearest round number.
Excuse me what? I’ve been an engineer for a decade and have never met anyone that would do that. We have calculators.
That’s how you know math is OP when you can calculate volumes in parallel worlds where circles don’t even looks like circles
They’re just rounding up from “3.”
And not that pussy rounding up where you go up by only 1, oh no, we’re rounding up 2 baby.
