Question 1208414: How many revolutions will a circular disk with a diameter of 4 feet have completed after it has rolled 20 feet?
Let me see.
I am tempted to use C = pi•d times the number of times the disk has rolled.
C = pi(diameter)(number of feet the disk has rolled).
C = pi(4)(20)
Is my setup correct? Answer by ikleyn(52863) (Show Source):
To be honest, I do not see any setup here, since this writing does not contain a complete equation.
The way for reasoning and for making setup is as follows.
Let n be the number of revolutions (same as rotations).
One rotation provides = feet move forward.
The setup equation is
= 20 feet.
The solution is n = = = 1.595727... rotations.
