A tank is filled with liquid of density p = 1000 (in kg/m³).Itsshapeisobtained byrotatingthecurvey = x²,0≤ x ≤ 2 around the y-axis. Find the work that is required to pump all the liquid out of the tank (from the top of the tank). All the lengths are in units of meter (m). Do not forget to use gravitational constant, g • A.
