Set up and evaluate the integral that represents the surface area of rotation of this cardioid about the -axis. Hint: Rotate only the right half of the cardioid, and use what you know about other surface area integrals to construct this integral.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
