V= $\"%28%284%2F3%29%28pi%29r%5E2h%29\"$ [isolate the r-term]
\n" ); document.write( " $\"%28V%2F%28pi%29h%29\"$ = $\"%28%28%284%2F3%29%28pi%29r%5E2h%29%29%2F%28pi%29h%29\"$
\n" ); document.write( " $\"%28V%2F%28pi%29h%29\"$ = $\"%28%284%2F3%29r%5E2%29\"$
\n" ); document.write( " $\"%283%2F4%29%28V%2F%28pi%29h%29\"$ = $\"%28%283%2F4%29%284%2F3%29r%5E2%29\"$
\n" ); document.write( " $\"%283V%2F4%28pi%29h%29\"$ = $\"%28r%5E2%29\"$ [take the square root of both sides]
\n" ); document.write( " $\"%28sqrt%283V%2F4%28pi%29h%29%29\"$ = $\"%28sqrt%28r%5E2%29%29\"$
\n" ); document.write( " $\"%28sqrt%283V%29%2F2sqrt%28%28pi%29h%29%29\"$ =r
\n" ); document.write( ".
\n" ); document.write( "check by plugging $\"%28sqrt%283V%29%2F2sqrt%28%28pi%29h%29%29\"$ =r back into the original equation (substitute it for the r-term) and solve. \n" ); document.write( "
