Extracted text: (a) Evaluate, with the order of integration being reversed, an equivalent integral of the following integral: r6-3x Lydydx. Draw a diagram to illustrate the process. (b) A hole is drilled through the center of a sphere x? +y² +z? = R;?, leaving a ring-shape solid. If the drill used is cylindrical in shape with radius Ra, use polar coordinates to formulate the volume V of the remaining solid.
