Volumes (Disk) Section 6.2 Problems 1-18 odd, 50-52 Formula for volume of revolution: v = Triedx, r is some function with variables a Instructions: Find the volume by drawing the regions revolving around the specific axis and using disks. (1) (6.2, Q8) Area enclosed by y = 6 - x2, y = 2, rotated about the x-axis. [Hint: should get 32 7] (2) (6.2, Q9) Area enclosed by x = y', r = 2y, rotated about the y-axis. [Hint: should get is 7] Section 6.3 Problems 3-20 odd Formula for volume of cylinder using cylindrical shells: v = 2rrhdD, r is radius, his height Instructions: Find the volume by drawing the regions revolving around the x axis and using shells. (1) (6.3, Q9) Area enclosed by ry = 1, x = 0, y = 1, y = 3 rotated about the x-axis. [Hint: should get 47] (2) (6.3, Q11) Area enclosed by y = x3/2, y = 8, x = 0, rotated about the x-axis. [Hint: should get 1927] 2
