Please use justification for each step.

(b) Using one of your parameterizations from part (a), compute the area of the region bounded
by C, x = 0 and y = %.
(c) Starting with the standard equation for this ellipse in rectangular coordinates, convert to
polar coordinates. If possible, find r(0).
(d) Rotate C about the x-axis to generate a solid. Set up, but do not evaluate, an integral to
compute the surface area of this solid using
i. one of the parameterizations in part (a)
ii. polar coordinates
iii. rectangular coordinates
(e) Which description of C is easiest to use to compute the surface area of the solid in part
(d)? Explain. If possible, compute the surface area using one or more of the integrals set
up in (d).
