Use a Computer Algebra System to Find the Exact Volume $$y = 4 x , y = 4 x e ^ { 1 - x / 2 } , \text { about } y = 16$$

Short Answer

Use a computer algebra system to find the exact volume of the solid obtained by rotating the region bounded by the given curves about the specified line. $$y = 4 x , y = 4 x e ^ { 1 - x / 2 } , \text { about } y = 16$$
