(a) Find the coordinates of each of these points.

The about finite the x-axis. region bounded by $\displaystyle C$ and $\displaystyle {\mathit{l}}_{\mathrm{,}}$ shown shaded in Figure $\displaystyle {\underline{{3}}},$ is rotated through $\displaystyle 360^{\circ}$

(b) Use algebraic integration to find, in terms of $\displaystyle \pi,$ the volume of the solid generated.
