Concept explainers

Cylinders

A cylinder is a three-dimensional solid shape with two parallel and congruent circular bases, joined by a curved surface at a fixed distance. A cylinder has an infinite curvilinear surface.

Cones

A cone is a three-dimensional solid shape having a flat base and a pointed edge at the top. The flat base of the cone tapers smoothly to form the pointed edge known as the apex. The flat base of the cone can either be circular or elliptical. A cone is drawn by joining the apex to all points on the base, using segments, lines, or half-lines, provided that the apex and the base both are in different planes.

Consider the plate bounded by y² = 8x and x = 2 with density 8 = 2 - x. 1. Sketch a graph of the plate. Shade in the region and number the axes so that the important points on the plate can be read from the graph. 2. Express the mass of the plate as a double integral and evaluate to find the mass. 3. Express the x-coordinate of the center of mass of the plate as a double integral and evaluate to find the value of . As a side note, by the symmetry of the plate and density, the y-coordinate of the center of mass y = 0. It might be good practice to confirm this though.
