Consider the region '1}? bounded by the x-axis and f (x) = 9'1"", where x F [0, 3]. a. Find the exact area of the region. b. Suppose ER is revolved around the x-axis. lGive a rough sketch of the resulting solid, and nd the exact volume of this solid using The Dise Method. e. Suppose ER is revolved around the line y = 2. Give a rough sketch of the resulting solid, and nd the exact volume of this solid using The Washer Method. Note that this time the solid has a hole
