For a sphere,
\n" ); document.write( " $\"V=%284%2F3%29pi%2AR%5E3\"$
\n" ); document.write( " $\"SA=4pi%2AR%5E2\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"%284%2F3%29pi%2AR%5E3=4pi%2AR%5E2\"$
\n" ); document.write( " $\"R=3\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
