Not sure why you’re getting downvoted. It’s how I solved it too. Just visualise the circle unrolling and see it covers one quarter of the bigger circle.
I probably would have gotten four because I would have visually saw the answer without knowing the equation.
I bet you would have discovered gravity first if only the apple fell on your head instead of pesky Newton
I don’t think that’s a brag.
Assuming they did what I did, they saw it and went ‘no fucking idea’ and visualised the wheel rotating and counting the rotations seen.
The smart people stuff is the trying to do the radius shit.
Correct, I wouldn’t have tried to apply a math equation, I would mentally roll it and count to get the answer. Nothing impressive about that.
Lots of people saw gravity in action, Newton figured out the equation.
