You can put this solution on YOUR website!
Did you mean 8 inches in diameter? If so, then the radius is 8/2 = 4, so r = 4.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "57 liters = 3478.35 cubic inches ----> V = 3478.35\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "V = pi*r^2*h\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3478.35 = pi*4^2*h\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3478.35 = 16pi*h\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "3478.35/16pi = h\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "h = 3478.35/16pi\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "h = 682.972425413379\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the pipe must be roughly 682.972425413379 inches long. \n" ); document.write( "

\n" );
