It’s 9 because imagine a ball on each side on circle a and then times those three by 3 and it will make a full loop but it stops on the circle before that’s because the last and 10th circle is already there so it’s 9 simple math you

The answer is F and the option is idk and just fail me
@lingjuanxu5196 Says:
Gambling time okay I got F
@Esmeralda-d1r Says:
Well the actual answer is four
@bananaglowstick Says:
Wtf dude
@MrAmol2912 Says:
Why did they did not give F on the exam paper?
@DaKoolDud30 Says:
The answer is 4, I hope my Asian parents will be happy
@MrAmol2912 Says:
I know what is the answer it’s four

@suvombiswas-t4o Says:
Answer is 8
@triview129 Says:
It's 4
@dmshot48 Says:
4 is the answer for this one. but think about a scenario where the small circle rotates inside the larger circle, how much revolutions would it take for the small circle to reach its starting point?
@abdullahsyedd Says:
its 3?
@liontribecub Says:
It’s 4
( I’m not smart js asked chat GPT )
@proisnotme Says:
Bruh and how
@great-brilliant.1 Says:
is it not 1??
@NapkinNexter Says:
4 when accounting for sidereal rotation
@Gorpgoop Says:
are u allowed to rip a strip of paper off to measure? seems easier to just measure it no?
@PeddintiSunita Says:
The correct 💯 answer is 4
@sushiljoshi2326 Says:
Answer is -- Four.
@sushiljoshi2326 Says:
Why did you start the video with all students get the answer wrong? That's the incorrect statement. The question itself was wrong.
@USA-CIA-NED_ProxyDeathSquadOps Says:
rotation(small1) to circum(big1)
=1 + 1/3
rotation(small2) to circum(big2)
=1 + 1/3
rotation(small3) to circum(big3=0)
=1 + 1/3
Total rotations(small)
= 3 (1 + 1/3)
= 3 + 1 = 4
@coreyycallahan Says:
Guys the answer is 4
@engineer378 Says:
4, consider large circle periphery a horizontal line. Then the small size will rovolute 3 time but the circumstance of large one is in circular form that will also add a one more revolution.

@cv4wheeler Says:
I have a fidget spinner composed of 9 interlaced gears of the same size in a 3x3 array. You hold the center gear stable by the frame and the outer 8 gears rotate around the center one, exactly like this. Since they are all the same size, you would think the outer gears would rotate once in a 360 degree loop of the whole thing, but they actually rotate twice.

@realoctopus Says:
W question
@mochannnnnnn Says:
I’m getting 4 cause wouldn’t be the rotation based on the imaginary circle whose new radius is a that of A plus radius of B so Ra plus (b)3ra is 4ra and then divide that by the circumference of a? But I guess it’s not it… Not part of the choices given - oh well.
Damn, I miss when my brain was sharp, I used to participate in our countries sigma contest- it’s a national math competition but you only get six questions… If wrong answer is a negative. No answer is zero right answer is plus ….the average was three out of six, lol

@NVSir-h9d Says:
If its pure rolling then it's very easy
@Flerovyttryt1 Says:
Answer is 3 , is it write
@Cavanjie Says:
Use a piece of thread to overlay the exact shape of the smaller circle ⭕️ and cut it where it meets . See how many times it fits round the edge of larger circle. Just looking and imagining this you can tell it’s more than three.

@jcoconuttt Says:
I think she erroneously added a half revolution adjustment thinking the center is lagged by half the circumference but it a rotating rigid body. Alternatively, she accelerates too fast and is accounting for slippage.
@Me_andthetable123 Says:
It's literally six
@dilrubakhan3561 Says:
Yes, the answer is 4
@MissM-c3t7k Says:
So Terrence Howard has hope then 😊

@hansbraun2726 Says:
I thought it was 3 originally but then I realized it was 4 because your creating a circumference of a circle radius 4r to get the center of the circle all the way to it's starting point
@THE_MASTERYING Says:
4?
@RicardoIramardosSantos Says:
Another point not mentioned, if you think that a line is an infinite sequence of dots one next to another, in a circle the dots are not in the same disposition.
@musicandsportpro Says:
Wrong answer optoins.
De radious of the smaller circle can be repeated four times between both centerpoints of the circles. So the correct answer for matching of their circumference is 4.
Meaning the smaller circle rols around 4 times.
1:3 radious becomes 4
1:1 radious becomes 2
1:2 radious becomes 3
1:0,5 radious becomes 1,5
1:0 radious becomes 1
Nice challenge 😃👍
@hannyjess7172 Says:
The answer is 4, it would be 3 if the path was flat but for circle there's an extra +1
