Whereas the density of the hemisphere at any point is proportional to it's density, then
The full answer in attachment, we use the partial integral using the <span>spherical coordinates,
and we find that </span>the mass of h = <span>πK/2</span>
It is in the thousandths place.
7+ (-5) = 2.
Therefor, 4^2 would be the right answer.
