You can put this solution on YOUR website!
( π k^2 -12k π + 36 π ) \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "π(k^2 -12k + 36) \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "π(k-6)^2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "It's in the form π*r^2, so r = k-6 \n" ); document.write( "

\n" );
