6.1 Exercises 13-28 even. Area between curves Instructions: Sketch the region enclosed by the given curves and find it's area. (1) (6.1, Q20) x = y', y = v2 - x, y = 0 (Hint: try integrating with dy) (2) (6.1, Q28) y = 1x2, y = 2x2, cty = 3,x 20 Volumes Formula for volume of revolution: v = / Fred.x, r is some function with variables Instructions: Find the volume by drawing the regions revolving around the specific axis. (1) (6.2, Q1) Area enclosed by y = r + 1, y = 0, c = 0, x = 2, rotated about the r-axis. (2) (6.2, Q7) Area enclosed by y = 23, y = x, I 2 0 rotated about the z-axis
