\"80%5Eo+%2A%28pi%2F180%5Eo%29+=+%284pi%29%2F9\"\r
\n" ); document.write( "\n" ); document.write( "==> \"s+=+r%2Atheta+=+9%2A%28%284pi%29%2F9%29+=+4pi\", the arc length portion of the sector.
\n" ); document.write( "Therefore, perimeter \"P+=+4pi+%2B+9++%2B+9+=+4pi+%2B18\" cm.
\n" ); document.write( "
\n" );
