Question 733785
Did you mean 8 inches in diameter? If so, then the radius is 8/2 = 4, so r = 4.



57 liters = 3478.35 cubic inches ----> V = 3478.35





V = pi*r^2*h


3478.35 = pi*4^2*h


3478.35 = 16pi*h


3478.35/16pi = h


h = 3478.35/16pi


h = 682.972425413379


So the pipe must be roughly 682.972425413379 inches long.
