31. In the Appendix to Chapter 12 we described the cycloid, which has the
parametric representation
* = u(t) = a(t – sin t), y = v(t) = a(1 – cos t).
(a) Find the length of one arch of the cycloid. [Answer: 8a).
(b) Recall that the cycloid is the graph of v o u. Find the area under
one arch of the cycloid by using the appropriate substitution in f
and evaluating the resultant integral. (Answer: 3ma|
Problems 32 through 44 use the material from Appendix 2 to Chapter 13.
32. (a) Find the volume of the solid obtained by revolving the region
bounded by the graphs of f(x) = x and f(x) = x' around the hori-
zontal axis.
(b) Find the volume of the solid obtained by revolving this same region
around the vertical axis.
33. Find the volume of a sphere of radius r.
34. When the ellipse consisting of all points (x, y) with x/a + y*/6? = 1 is
rotated around the horizontal axis we obtain an "ellipsoid of revolu-
tion" (Figure 2). Find the volume of the enclosed solid.
