You can put this solution on YOUR website!
volume of a cylinder = area of base * height = pi*r^2 * height
\n" ); document.write( ".
\n" ); document.write( "we are told volume = 91 and r=4
\n" ); document.write( ".
\n" ); document.write( "91 = pi(4^2) * h
\n" ); document.write( "91 = pi(16) * h
\n" ); document.write( "91 = 16pi * h
\n" ); document.write( ".
\n" ); document.write( "dividing by 16*pi
\n" ); document.write( ".
\n" ); document.write( "91/(16*pi) = h
\n" ); document.write( ".
\n" ); document.write( "so the height is about 17.8678 in.
\n" ); document.write( ".
\n" ); document.write( "done
\n" ); document.write( "
\n" );
