<PRE><B>Question 368712</B>
The arc length s is given by the radius times the angle theta, or &lt;br&gt;

s=r*theta&lt;br&gt;

But the key to this problem is that we need to know the measure of theta in RADIANS!&lt;br&gt;

So 12 degrees equals how many radians?&lt;br&gt;

12 degrees = [(pi/180)*12]radians or&lt;br&gt;

theta=pi/15 radians&lt;br&gt;

So, our arc length is given by&lt;br&gt;

s=r*theta&lt;br&gt;

s=2*(pi/15)&lt;br&gt;

&lt;b&gt;s=(2*pi)/15 inches &lt;/b&gt;&lt;br&gt;

which you can approximate using the value of 3.1415926... for pi.&lt;br&gt;

I hope this helps!&lt;br&gt;</PRE>
