C = pi*d\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "C = 3.14*21\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "C = 65.94\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the circumference is roughly 65.94 units .
