Background: A souvenir company plans to manufacture commemorative paperweights made of variable density metal. In the company's design specifications, each paperweight is modelled as a solid region V satisfying the conditions: x² + y² + x² ≤ 2, z ≥ √(x² + y²) The mass per unit volume (mass density) of Vis p(x, y, z) = 9z. and y ≤ 0. Before manufacture, the company needs to compute the mass of each paperweight, to determine shipping costs. They also need to compute the surface areas of the curved surfaces of each paperweight, as they plan to paint these surfaces, and need to determine the volume of paint required (which is proportional to the surface area). (a) Sketch V. (b) Calculate the mass of the paperweight, using cylindrical coordinates. (e) Calculate the mass of the paperweight using spherical coordinatos
