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…
Or it’s from an ME. They seldom can remember the rounded value of Pi, but they’re pretty sure it’s somewhere between 3 and 4. But you probably should use 5 just to be safe…
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.
This is how the wealthy calculate their tax exemptions.
Idk, if you want to test people on how they understand formulae and order of operations without letting them just punch it into a calculator. The actual math isn’t hard, but if you don’t get substituting values into an equation then it’s not trivial
When you want students to not use calculators but still rate a question for 10 second answer.
π = 5 for very small values of r.
New New math
That just means the curvature of spacetime is negative.
This physics class?
Astronomy.
My favorite is when doing Order of Magnitude estimations, you are supposed to let pi = 1
The answer is substantially different though. 3141 units (rounded correctly) vs 5000. That’s a significant margin that even working it out in your head is not forgiving enough to cover.
Unless I fucked up.
Ah, Indiana math.
…in spacetime with high curvature?
Makes me miss the days of 22/7.
