Centroid of an Ice-Cream Cone
A delicious ice cream is shown in the figure. The density of the hemispherical ice-cream top is 'densic' and the density of the cone
part is 'densco'. All distance dimensions are inches.
Find:
(1) ycream, zcream, the y,z coordinates for the centroid of the ice cream top
(2) ycone, zcone, the y,z coordinates for the centroid of the cone
(3) ycomb, zcomb, the y,z coordinates for the centroid of the ice cream and the cone together
(4) ymass, zmass, the y.z coordinates for the center of mass of the entire system
