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.
im guessing id have to do ρdxdydz, and maybe use polar coordinates but I am completely lost. I am used to the question giving me an equation for the density which this doesn't have.
Any help would be much appreciated
(This is an exam question i had today but failed miserably at!)
