You can put this solution on YOUR website!
S=r*Theta, where S = Arclength, r=radius, and Theta= angle measured in radians.\r

\n" ); document.write( "\n" ); document.write( "\"3+%2Api=12+Theta\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Divide both sides by 12,
\n" ); document.write( "\"Theta+=+pi%2F4=180%2F4=45+degrees\"\r
