The volume of a sphere is given by:
\n" ); document.write( " $\"V+=+%284%2F3%29%28pi%29r%5E3\"$ Substitute $\"V+=+%28288%29%28pi%29\"$
\n" ); document.write( " $\"288%28pi%29+=+%284%2F3%29%28pi%29r%5E3\"$ Divide both sides by $\"pi\"$
\n" ); document.write( " $\"288+=+%284%2F3%29r%5E3\"$ Multiply both sides by the multiplicative inverse of $\"4%2F3\"$ which is $\"3%2F4\"$ .
\n" ); document.write( " $\"216+=+r%5E3\"$ Take the cube root of both sides.
\n" ); document.write( " $\"highlight%28r+=+6%29\"$ cm. \n" ); document.write( "

\n" );
