I’d have torn out a little circle from my scratch paper and done it my self
@makoto3190 Says:
The awnser is 3.
Devide the circumference of circle B by circle A.
Circumference of circle is: 2*π*radius
The trick is: Do not round up any decimals.
It could be possible that not all calculators could handle the precision needed for that awnser to show up, as you need to use 10 decimals.

I rolled the circle around the bigger one in my head and decided the answer was 9/2
@neilrogers6767 Says:
4
@fatwildcatify Says:
In my opinion it is 4.
Suppose the radius of B is 0. The circle A will rotate once. So, value 1 must be added to the radii ratio.
@herbertwilliams411 Says:
I assumed that the picture was correct and just counted how many times I would need to put circle A to reach the middle counting the current position as 1. If you cut circle a in half and count it 3 times it would be exactly in the middle using 2 circles so a 3/2.
I pick A and I know it’s crazy but I also question why I would want a job where I need to count how many circles are inside a bigger circle.
@Draconatus24 Says:
Called it. If nobody got it right that means none of them were right because we all know there will inevitably be those people who choose randomly and one of those people would get it right if there were a right answer.
@jeremyarrieta6869 Says:
The answer is 4
None of the given options directly say 4, so it might be a trick about the way you interpret it.
@jeremyarrieta6869 Says:
Even chatgpt couldn’t answer this. 😂😂😂
@jus-ta-terminator19 Says:
Can the answer be 4? Like when the smaller circle rolls around the bigger circle, a new circle would be formed with radius 4. now if we divide the circumference of this new circle with the smaller circle, we would get 4.

We had a not so similar issue in a physics exam one day. So our professor liked to have a few usually 3 questions with two possible answers. How? Some of them were in different units (at first I thought they were not correct as we are taught the universal unit system or however it's called as the only sizing units and the rest are correct but to not use them) like m/s and k/h. Both answers equated to the same value like 60 km/h is the same as (or around) 16,6666 m/s. He usually told you how many of these there were at the beginning of the test so people couldn't just mark two answers out of all questions. He said if we somehow found an extra one he wouldn't remove points. But would if he spotted some cocky ones that marked a ton of answers as having more than one correct. This one time he said there were two but actually there were three. Because of this he added an extra point to everyone but I still failed mine that day. I did eventually pass it but you can see why he had to increase the points. Because people would've only looked for 2 in order to not get extra points taken off for being cocky. Also if he said there were 2 people wouldn't really look into the answers too much to verify any more had two possible correct answers. Or might've thought that he did it on purpose to throw you off. Like if there's only two of them, he must've written that other question like that to throw off people who didn't study all too well as it sounds possible so I'm not going to mark that one as a double possible answer.
@IlmWiz Says:
Correct answer is 4
@atreidesson Says:
It's not called "got wrong" then. If the student was wanting to answer "4" and there was no such option.
@wisteria3032 Says:
The answer would be 3 if it revolved on a straight line.
Since it revolves around a circle the answer is 4: the 3 revolutions it needs for the distance plus another one for going around a circle. (A lot easier to see if you imagine it revolving around a point: it revolves once instead of staying still. Then you try with two equal circles. It revolves twice instead of once)
@ciprianmarinescu8274 Says:
There is no way someone didnt randomly choose and got it right
@leannegray9953 Says:
I really hope this isn't one of our unanswered mathematical questions as I can demonstrate that the answer is 4.....
@sergioromero9932 Says:
Why this guy never gives answer?....😮
@mkerengajames Says:
keyword "the center of circle A" thats what makes 3 not the answer. unless the question stated "both radius to return to initial positions"
@jameslowe66 Says:
the answer is purple.
@chriskyng2509 Says:
Funny... my answer was none of the above, but its because I completely misunderstood the question and read it as a trick question instead (which math teachers famously love using to screw with their pupils).
@palfreyPodcast Says:
I just learned circles are complex af
@videos_not_found Says:
SATly I cannot...
@jessepiologo8504 Says:
Answer is roughly 2.5
@baila3221 Says:
I feel like I could answer it with a piece of string.
@AIWIndustries2223 Says:
This is the type of question I’d just circle a random answer because I have no idea what it is
@Nooby_Dev1234 Says:
Answer is 4
@BangleWish Says:
It should be 6.
@thomashenden71 Says:
And what was the answer…? The video ended before @Veritasium finished his explanation…
@DanetteBall Says:
Vsause would have given us the real answer, plus explained how the test makers messed up, plus provided told us about how a dog somehow got it right.
@demZetri Says:
My guess is 4, based on trying to eyeball it. Not the most scientific, but better then not trying at all.
@coreyscolaro288 Says:
Damn so whats the answer
@mrnnhnz Says:
The Emperor is nude, and the answer IS three. Unroll both circles (imagine they're made of string,) and one is one third the length of the other - we're told that in the problem set up. Three of the smaller one = 1 of the bigger one. And that's the answer.
@mikedavis979 Says:
so,depends on how you define 'rotation', your point of reference.
@KissMyArs-n9t Says:
Good thing I'll never run into this problem in real life ever just on some test some virgin came up with.
I don't give a shyt is the answer
@broc2727 Says:
3 is the answer for how many licks it takes to get to the Tootsie Roll center of a Tootsie Roll.

@bigturk83 Says:
I got 4 but it wasn’t an option so figured I did it wrong haha
@iamrightyouarewrong4378 Says:
The question is often misunderstood as to when will A end up in the same position (after 3 turns) but the question is when the center is facing the same direction again (turns 90 degrees with every turn = 4 revolutions) Its much easier to visualize the problem, if you replace the center with a shape
@RQ10V Says:
Sorry I don’t know, I wasn’t even listening sir
@ninja_kitten-1 Says:
I mean I choose C because B seemed small
@Felendore_ Says:
It doesn't say 'rotations' of Circle A, but rather how many times Circle A must travel around Circle B- that's how I understood it based on the writing.
Which means Circle A must travel around Circle B once in order to reach its starting point.
@arturo0727 Says:
You can't tell us, answer B is wrong without telling us the right answer. How dare you. 😂😂
@mollysmoshingtankcrew9441 Says:
How can everyone get it wrong? Surely someone randomly guessed the right answer. At least once.
@DRICH1394 Says:
Damn near had Claude self destructing trying to wrap its mind around the write answer not being there🤣🤣
@MahmoudAbdelateShalaby Says:
answer near by ((4/3)rπ), (r: radius of circle B)
'cuz we count how many jumps the center of circle A can take on a circle it make and its center is the center of circle B, we count this number of jumps by dividing the 2πr of this new circle by 2 of the radius of circle A, then it is near by ((4/3)rπ), (r: radius of circle B).
I'm an Egyptian high school student.
@DeveloperFox Says:
The real answer is actually 4, because think of B with a cross in the middle, A rolls to the top, that's 1, then to the side, that's 2, then to the bottom, that's 3, then to the side again, that's 4. A would also be rolling in the process, so it's taken 4 revolutions
@gregtaylor3432 Says:
The center of circle A will return to the starting position each and every time it completes a rotation around circle B. Thus none of the presented answers are correct in regards to the posted question.
