You can put this solution on YOUR website!
I assume that your equation looks like:
\n" ); document.write( "S(2r) = $\"%281%2F3%29%28pi%29r%5E2%282r%29\"$
\n" ); document.write( "
\n" ); document.write( "(1) r^2(2r) = 2r^3
\n" ); document.write( " $\"%281%2F3%29%28pi%29%282r%5E3%29+=+0%29\"$
\n" ); document.write( "
\n" ); document.write( "(2) Divide both sides by 2(pi)/3
\n" ); document.write( " $\"r%5E3+=+0%29\"$
\n" ); document.write( "
\n" ); document.write( "(3) Cube root both sides. You are left with:
\n" ); document.write( "r = 0 \n" ); document.write( "

\n" );
