You can put this solution on YOUR website!
The circumference ( distance around ) = \"+2%2Api%2Ar+=+300%2Api+\"
\n" ); document.write( "\"+300%2Api+=+942.3+\" m
\n" ); document.write( "\"+942.3+%2F+13+=+72.5+\" m/min
\n" ); document.write( "\"+72.5%2A%28+1%2F60+%29+=+1.21+\" m/sec
\n" ); document.write( "
\n" );
