A solid ball of radius a has density given by (2a-p) where p = sqrt(x^2 + y^2 + z^2). Determine its mass.
a) I think it's properly setup by converting to spherical, still iffy if (2a-p)=(2p-p)=p
b) What did I just find and how do I then get mass?Thanks-a-centillion if you reply, this isn't homework, but is part of a practice midterm.
