Social Activity Token (SAT) Reviews & Critics
Problem: Circle A has 1/3 the radius of circle B, and circle A rolls one trip around circle B. How many times will circle A revolve in total? 1982 SAT Question In the ....
- I think the question is correct as the keyword is revolve but not rotate. Revoke implies the rotation is relative to circle B while Rotate implies the rotation is relative to ground. Agree?
- How many times will it roll from the perspective of the center of the small circle, or from the perspective of the large circle. To see this stand at the center of the small circle facing the point P where the small circle touches the large circle. From that perspective one revolution means that you are once again facing the center of the large circle, that point P will again touch the large circle, when you are again facing the center of the large circle. The point P will touch the large circle when you have rolled 1/3 of the length of the diameter of the large circle. Refer to Sander's comment. The answer is 3 or 4 depending on your reference coordinates.
- I could not understand your mathematical proof of the correct answer. Please explain the proof and make us understand.
- wait.. what?
