help understanding polar equation of circle
In a problem i am working on, equation of the circle is given to be
$x^2+y^2-2ax=0,z=0$
So the polar equation taking become $r=2a\cos\theta$
So for the purpose of surface integral, $r$ varies from $0$ to
$2a\cos\theta$ and it is given that $\theta$ varies from $0$ to $\pi$
should it not be till $2\pi$ ?? The integral is to be determined above the
plane $z=0$
