YouTube brings a SAT question.
We have a circle of radius that is 1/3 of the radius of another circle.
They ask how many times the smaller circle goes around the bigger circle.
The answer should be 3: 2 Pi r/3 would be the length of the circumference of the smaller circle.
With this, we need to multiply it by 3 to get 2 Pi r, which is the circumference of the bigger circle.
That means that the length of the smaller circumference will mean 3 turns over the bigger one for it to go back to the initial point.
