1. The problem statement, all variables and given/known data The density of material at any point in a solid cylinder, y^2 + z^2 ≤ a^2, 0 ≤ x ≤ b is proportional to the distance of the point from the x-axis. Find the density. Use k as the proportionality constant. 2. Relevant equations 3. The attempt at a solution Can someone guide me here? is x here a?
