The question ONLY asks for a graph of the polar equation.
Given $r = 3\sin θ$
Table of Values:
$(0, 0)$
$(3/2, \frac{\pi}{6})$
$(1, \frac{\pi}{2})$
$(3/2, \frac{5\pi}{6})$
$(0, \pi)$
$(-3/2, \frac{7\pi}{6})$
$(-1, \frac{3\pi}{2})$
$(-3/2, \frac{11\pi}{6})$
See graph below. It is in the shape of a circle.
