Homework Statement
W is the solid bounded above by [tex]\rho[/tex]=3 and below by[tex]\phi[/tex]=[tex]\pi[/tex]/3, calculate the mass W if the density at each point is directly proportional to the square of its distance above the xy plane.
The Attempt at a Solution
I am having a difficult time starting out this problem, I am assuming I need to use spherical coordinates considering the problem is given in terms of rho and phi, however it says bounded above by rho=3 and below by phi =pi/3, I thought phi determined the angle from the z axis to rho??
Any thoughts direction would be appreciated
