2 The function defined by y=√r² - x² has as its graph a semicircle of radius r with center at (0,0) (as shown in the figure to the right). Find the volume 2 that results when the semicircle y = V√49-x² is rotated about the x-axis. The volume is cubic units. (Type an exact answer, using è as needed.)
