a) The shaded area enclosed by the curve y = x? - 4 and the x-axis is rotated around the x-axis to form a solid of revolution. Calculate the volume of the solid formed. b) The same curve y = x² - 4 bounded by the y-axis and the lines y = 0 and y = 2, is rotated around the y-axis to form a solid of revolution. Calculate the volume of the solid.
