        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.

          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.

      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.
