2. (13 points) A solid has a quadrilateral base (four straight edges) with vertices at (-2,0), (0,6), (2,-2), and {12,3) and semi-circular cross sections perpendicular to the base. Note: If you clearly define a function (for example f(z) = %) then you can reference the name of the function without rewriting it entirely ( || : f(x)dx rather than [ : e da). (a) Set up the integral(s) that represents the volume of the object when the cross-sections are parallel to the y-axis. (b} Set up the integral(s) that represents the volume of the object when the cross-sections are parallel to the r-axis
