QUESTION 2 Let a mass density be p(x,y) = 4y kg/m². Find the total mass at the side surface of a cylinder: S:{x² + y² = 16, x>0, y > 0, 0 <z<10} that is bounded by the coordinate planes in the first octant. Insert your answer below without any unit, round to closest decimal in tenths (if you found 3.54 and put 3.5, if 3.56 then put 3.6), if needed.
