4. Evalute the following: (a) The region bounded by y = (3-2)' y = 0, x = 1, and x = 2 is revolved about the x-axis. (b) The region bounded by y = 1-x2, x = 0, x = 1,is revolved about the line x = 1. 22 7 5. The rational number has been used as an approximation to the number since the time of Archimedes. Show that **(1-2) dr = 22 dx 7 4. Evalute the following: (a) The region bounded by y = (3-2)' y = 0, x = 1, and x = 2 is revolved about the x-axis.
