I think you are supposed to use arc length formula.

This is what I got so far:

How far to the nearest hundreth cm, does the tip of the hour hand on a clock move in exactly 3 hours if the hour had is 2.00 cm long?

I think you are supposed to use arc length formula.

This is what I got so far:

the hour hand of an analog clock moves 1/12 of a revolution in one hour.

$s = r \cdot \theta$
