![**Problem Statement:**
Use cylindrical coordinates to find the mass of the solid \( Q \) of density \( \rho \).
**Definition of Solid Q:**
\[ Q = \{(x, y, z) : 0 \leq z \leq 9 - x - 2y, \, x^2 + y^2 \leq 64 \} \]
**Density Function:**
\[ \rho(x, y, z) = k \sqrt{x^2 + y^2} \]
**Description:**
The solid \( Q \) is defined within a cylindrical boundary. The first condition \( 0 \leq z \leq 9 - x - 2y \) confines the height of the solid between 0 and a plane defined by \( 9 - x - 2y \). The second condition \( x^2 + y^2 \leq 64 \) describes a circular region in the xy-plane with a radius of 8. The density \( \rho(x, y, z) \) is dependent on the radial distance from the origin in the xy-plane, scaled by a constant \( k \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffa48f7eb-bce8-4ea0-bf8b-7482c9c56a7c%2F313d4838-7ef6-428f-8c21-ee5e9b61280e%2Fufhqpsb_processed.jpeg&w=3840&q=75)
