Use the Shell Method to compute the volume of the solid obtained by rotating the region above the x-axis and below the graph T about the y-axis, where 0

A volume is described as follows: 1. the base is the region bounded by y = 9 - 9x² and y = 0 2. every cross section parallel to the x-axis is a triangle whose height and base are equal. Find the volume of this object. volume =

Find the volume of the solid obtained by rotating the region A in the figure about y = -4. y =x² +b b a Assume b = 2 and a = 4. (Give an exact answer. Use symbolic notation and fractions where neęded.) volume:
