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.
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...
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.
