![**Problem Statement: Finding the Volume of a Solid**
Find the volume of the solid bounded below by the circular cone:
\[ z = 2\sqrt{x^2 + y^2} \]
and above by the sphere:
\[ x^2 + y^2 + z^2 = 2.25z. \]
**Instructions:**
To solve this problem, you will need to set up and evaluate a triple integral. Consider converting to cylindrical or spherical coordinates, as this problem involves a cone and a sphere. Determine the limits of integration by finding the points of intersection between the cone and the sphere.
1. **Converting and Simplifying:**
- Simplify the equation of the sphere and consider symmetry.
- Analyze the cone's equation in a suitable coordinate system.
2. **Finding the Intersection:**
- Solve for the points where the cone intersects the sphere. This will help in establishing the limits of integration.
3. **Setting Up the Integral:**
- Use the appropriate coordinate system to set up the integral that represents the volume of the solid.
4. **Evaluating the Integral:**
- Calculate the value of the integral to determine the volume of the solid.
**Note:** Ensure all computations are accompanied by detailed explanations to enhance understanding.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F91ed8060-678c-4d36-a5c7-0e7a65a577a0%2Fd20e740b-98f6-4c32-897d-7e7c24430e08%2Fle43i2_processed.png&w=3840&q=75)
