    Clock is like a circle, right? So again, you have to walk along the edge.

    the hand is 8 inch, which is the radius. and the tip of the hand is walking along the circumference|dw:1439305318782:dw|

    now you need to know how much of that circumference is the tip walking. in other words, how many circles does it walk. in 1 hour it walks 1 circle. makes sense, yeah?

    The formula for the circumference is \[2*\pi*R\]
