The Correct Answer or the Most Helpful One?

And option C: "Talking with your boss about this issue" isn't available? :x



I don't see the issue here: You can perfectly well state both the correct and the helpful one. Or even better: The helpful way to understand the correct one.

Russt: Pi is the ratio of the radius and the circumsphere. Not the diameter (at least I think of the diameter when you say across).

But when you line up circles to measure how long the "string" is, saying that it's 6 radius long is more incomprehensible for children than 3 diameter (which happens to be one unit per coin) long. And formulaically, it's the same thing.

And lmao, I wish my teachers had used a similar approach.
