14. What is the approximate volume of the solid created when the region under the curve y = x3 on the interval [0, 2] is rotated around the QE-aXlS? 15. What is the approximate volume of the solid created when the 7T 71' region under the curve 3; = cos :c on the interval [ 3, 5] is rotated around the a: (1232's ? (Set this up algebraically, but then feel free to use a graphing calculator to evaluate the integral.) 16. Find the volume of the solid created when the region bounded by y : 3, y : and a: : 0 is rotated about the y-axis. 0817
