The density per unit area of a circular lamina of radius a varies as the cube of the distance from a single point on the edge. Find the mass of this lamina.(adsbygoogle = window.adsbygoogle || []).push({});

im guessing id have to do ρdxdydz, and maybe use polar coordinates but im completely lost. Im used to the question giving me an equation for the density which this doesnt have.

Any help would be much appreciated

(This is an exam question i had today but failed miserably at!)
