A large metal disk with radius of 3 m has been made. The density of the metal disk is given by p(x, y) = 5 + 2xy kg/m². A section of the disk from 0 = 0 to 0 = #/3, as shown in the figure below. Note: the diagram is only a representation of the problem, and does not show the 0 angle accurately. Determine the mass of the shaded piece. Mass of shaded piece ? (Answer should be rounded to 2 decimal places) Hint: This problem is easier in polar coordinates.

Question
A large metal disk with radius of 3 m has been made. The density of the metal disk is given by p(x, y) = 5+2ry kg/m². A section of the disk from 0 = 0 to 0 = a/3, as shown in the figure below. Note: the diagram is only a representation of the problem, and does not show the 0 angle accurately. Determine the mass of the shaded piece. Mass of shaded piece ? (Answer should be rounded to 2 decimal places) Hint: This problem is easier in polar coordinates.
