How do I acquire the bounds for the triple integral?

**Volume of a Solid Bounded by a Cone and a Sphere**

To find the volume of the solid bounded below by the cone \( z = \sqrt{x^2 + y^2} \) and above by the sphere \( x^2 + y^2 + z^2 = 162 \), we use a triple integral.

**Graphical Explanation:**

The diagram displays a three-dimensional coordinate system with the \( x \)-, \( y \)-, and \( z \)-axes. 

1. **Cone:** 
   - The cone is represented by the equation \( z = \sqrt{x^2 + y^2} \). 
   - It is shown as a blue, inverted conical shape with its apex at the origin \((0,0,0)\) and extending upwards.

2. **Sphere:**
   - The sphere in the diagram is described by the equation \( x^2 + y^2 + z^2 = 162 \). 
   - It is depicted as a yellowish cap that sits atop the conical portion.

3. **Intersection:**
   - The two surfaces intersect at a circle in the \( xy \)-plane.
   - At the top of the sphere, a point labeled \((0,0,\sqrt{162})\) indicates the z-coordinate of the uppermost part of the sphere.

By setting up a triple integral in cylindrical or spherical coordinates, we can calculate the volume of the solid region that lies within these bounds.
