Consider a cone of height h radius r = = 4. Let the cone be oriented so that the base sits on the x-axis and the y-axis runs through its center. Using the shell method, the volume of the cone is: V shell = where a = a Va washer where a = V = = 12 with a circular base of b and b Using the disk method, the volume of the cone is: b - 1² = = dx and b = dy Use either method to compute the volume:
