For a cylinder, the volume is,
\n" ); document.write( " $\"V=pi%2AR%5E2%2AL\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"V%5Bp%5D=pi%2Ar%5E2%2A10\"$
\n" ); document.write( "and
\n" ); document.write( " $\"V%5Bq%5D=pi%2A%282r%29%5E2%2Ah\"$
\n" ); document.write( "Since the volumes are the same,
\n" ); document.write( " $\"10%2Api%2Ar%5E2=4h%2Api%2Ar%5E2\"$
\n" ); document.write( " $\"2h=5\"$
\n" ); document.write( " $\"highlight%28h=5%2F2%29\"$ $\"cm\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
