Density of Solids

The density of a substance refers to how much matter is present in a given amount of space. It is expressed as the ratio of the mass of the substance to its volume.

Question

Suppose that a thin metal wire in the shape of a semicircle occupies the curve C, where C is the top half
of the circle x² + y² = 16. The mass density of the wire is described by the function p(x, y) = x³y. Find
the total mass of the wire.
