You can put this solution on YOUR website!
The arc length s is given by the radius times the angle theta, or
\r
\n" ); document.write( "\n" ); document.write( "s=r*theta
\r
\n" ); document.write( "\n" ); document.write( "But the key to this problem is that we need to know the measure of theta in RADIANS!
\r
\n" ); document.write( "\n" ); document.write( "So 12 degrees equals how many radians?
\r
\n" ); document.write( "\n" ); document.write( "12 degrees = [(pi/180)*12]radians or
\r
\n" ); document.write( "\n" ); document.write( "theta=pi/15 radians
\r
\n" ); document.write( "\n" ); document.write( "So, our arc length is given by
\r
\n" ); document.write( "\n" ); document.write( "s=r*theta
\r
\n" ); document.write( "\n" ); document.write( "s=2*(pi/15)
\r
\n" ); document.write( "\n" ); document.write( "s=(2*pi)/15 inches
\r
\n" ); document.write( "\n" ); document.write( "which you can approximate using the value of 3.1415926... for pi.
\r
\n" ); document.write( "\n" ); document.write( "I hope this helps!
