Question 1200020
.
the minute hand of a clock is 11 inches long. 
How far does the tip of the minute hand move in 20 minutes
~~~~~~~~~~~~~~~~~~~~~


<pre>
In 20 minutes, the minute hand of a clock makes 1/3 of the full revolution 
(because 20 minutes is 1/3 of an hour).


So, the tip of the minute hand moves 1/3 of the circumference

    the traveled distance = {{{(2*pi*r)/3}}} = {{{(2*3.14*11)/3}}} = 23.0267 inches.    <U>ANSWER</U>

Solved.
