Has the imperial system gone to far?
(feddit.org)
It's probably trying to teach kids algebra without using decimals. But it does look messed up. Everyone knows at least 3.14, except kids I guess
I got my daughter to memorize 50 digits of pi when she was 11 or 12 by betting her $50 she couldn’t.
I'll remember that, but she is four now....
I'm fine with 3, maybe 4, but 5????
I don't understand. Aren't fractions better than decimals for algerba?
Like 22/7 is better than 3.14 when it comes to pi for example.
We always got taught to do everything as fractions and then convert to units at the last possible moment to reduce errors in rounding.
My dad told me a rhyme to memorize like 15 digits of pi before I knew what pi is at like eight years old I'm guestimating. I remember it ever since.
... Yet refuses to share it with the world!
It's in a different language.
might also be to teach actually reading the instructions instead of blindly typing pi into the calculator

This was written by an engineer. They rounded up to 5 for the safety factor.
What kind of problem gives you the formula and all variable to replace? At this point, why not just write 5•10²•10=?
Intro to algebra type stuff to make sure you understand the concept of variables in the first place
Even then, I would want them to leave π in the problem itself. That would be much better for this exercise - teaching that you report “exact” values with π still in them.
Eg, if I rewrote this problem, I would expect an answer of 1000π.
Pi= 5 in this teachers reality. Circles must look wonky.
It makes it easy to do the math in your head without a calculator. But still , just tossing out pi=5 is not the way to go about creating these problems.
...fractal circumferences can be whatever length you want for any given mean radius...

Cause reading comprehension is part of the test. Lots of kids will be able to solve that equation, but there's a bunch who can't understand it if it's presented this way.
Honestly here they should have done "round pi to two decimal places" or smth.
Assigning a value of 5 to pi, although ludicrous IRL, doesn't affect the problem. Plug the values into the equation and it will still give an answer that's correct in context.

It's official, the observable universe is ~3 times larger!
Bye, bye, miss American PI.
Maybe Vader some day later, but now it's just about prime.
In America, numbers are just bigger.
Bigger numbers are better numbers!!!!! The best in the world!!!!!!1!11!!!11!
It’s clearly just saying that the surfaces on which the ends of the cylinder lie are metric spaces with distances defined using Chebyshev or Taxicab metrics based on pentagonal tilings of the parabolic plane so the ratio of a circle’s circumference to diameter is 5.
Since it’s a cylinder we assume the vertical dimension is Euclidean and voila the math checks out geometrically.
Whoa, amazing!
Astrology is so cool
Ha Ha, non-Euclidian geometry go brr. :)
This question was written by an engineer
In combat conditions Pi can reach 4 and E can reach 3. Maul halten und weiter dienen, all that.
OK. I might be thinking too much into this, but the metric system is good for practical use, but bad for didactic purposes. Some things which could use understanding are "automated" with the metric system.
So making Pi a variable is ... fine. Maybe it's some different geometry where it is.
Ah yes, all those imperial units...
This is how you develop trust issues.
