The above question is currently ambiguous and can be more clear by stating the distance mentioned is along the circumference. Currently it interprets to the euclidean distance as between the two points is 16π, which is not the intention of the question.
Does “on” vs “along” create a difference in interpretation?
You are right. This doesn’t clear the ambiguity as well.
I hope you get my concern that the question doesn’t state that the distance mentioned is measured along the circumference, it just states that the points are on the circumference and doesn’t say anything about the distance being measured along the circumference.
The correct way would be something like (I believe your team can frame it better than me):
“The largest distance measured along the circumference between two consecutive points on the circumference”.
Done.
Thanks!
