i had to do this some time ago:(adsbygoogle = window.adsbygoogle || []).push({});

assume you have a large cloud or radius 2 km, and its density is defined as D(ro) = 3 - ro (btw i cant find the letter 'ro' anywhere... )

what i the mass of the cloud?

i did it this way: mass = density * volume, so in this case it equals D(ro) * dV, so integrating (triple integral) over V yeilds (triple integral) (3 - ro) * (ro)^2 sin (phi) d ro d theta d phi. is that right?

i hope you can understand my *terrible* notation
