You can put this solution on YOUR website!
A = \"1%2F7\"\"pi%2Av%5E2r\" solve for r
\n" ); document.write( "multiply both sides by 7
\n" ); document.write( "7A = \"pi%2Av%5E2r\"
\n" ); document.write( "Divide both sides by \"pi%2Av%5E2\"
\n" ); document.write( "\"%287A%29%2F%28pi%2Av%5E2%29\" = r
\n" ); document.write( "
\n" );
