(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A string is wound tightly around a wheel. When the end of the string is pulled through a distance of ? cm, the wheel rotates through ? revolutions. What is the radius of the wheel?

2. Relevant equations

3. The attempt at a solution

i'm confused about this simple problem because i believed that displacement and revolutions were the same for theta in a kinematics problem like this: theta = 1/2(w0 + w)t

what equation would I use to solve such a problem.
