barnacle was underwater

Answer: +When the graph is below the x-axis, the barnacle is underwater.

+The graph dips below the x-axis three times between x = 0 and x = 20, so the barnacle goes underwater three times.

+Every time the barnacle goes underwater, the boat travels pi meters (one half the circumference of the wheel) before the barnacle comes back up, so the barnacle covers 3pi  meters underwater between x = 0 and x = 20
