if the hand of the clock is 10 cm long how far will it move within 1 hour
==========================
Do it like this one:
the hand of the clock is 2 cm how far will it move within 1 hour
------------
1 hour = 1/12 of a revolution = 30 degs, or pi/6 radians.
----
Arc length = r*angle
= 2*(pi/6) cm
= pi/3 cm
=~ 1.047 cm
