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.
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.
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.
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
Pi= 5 in this teachers reality. Circles must look wonky.

…fractal circumferences can be whatever length you want for any given mean radius…
