You mean you know the arc length and the angle corresponding to the arc length.
\n" ); document.write( "If $\"AL\"$ is arc length, $\"C\"$ is circumference, $\"theta\"$ is the angle in radians, then
\n" ); document.write( " $\"AL%2Ftheta=C%2F%282%2Api%29\"$
\n" ); document.write( " $\"C=%282%2Api%2AAL%29%2Ftheta\"$
\n" ); document.write( "Since the circumference is the arc length when the corresponding angle is $\"2%2Api\"$ radians.
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "If the angle is in degrees, then,
\n" ); document.write( " $\"AL%2Ftheta=C%2F360\"$
\n" ); document.write( " $\"C=%28360%2AAL%29%2Ftheta\"$ \n" ); document.write( "
