![### Educational Content on Double Integration
#### Problem Statement
Evaluate the double integral \( \iint_{D} \sqrt{x^2 + y^2} \, dA \), where \( D \) is the domain specified in Figure 4.
#### Figure 4 Explanation
Figure 4 presents a diagram featuring two circles. The larger circle is centered at the origin (0,0) and denoted by \( F \). Its equation is \( x^2 + y^2 = 36 \), indicating a radius \( R_f = 6 \).
The smaller circle is labeled \( G \) and is centered at (3,0). The equation for \( G \) is \( (x-3)^2 + y^2 = 9 \), which corresponds to a radius \( R_g = 3 \).
Domain \( D \) is the area enclosed between these two circles.
#### Given Parameters
- **Equation of Circle F**: \( x^2 + y^2 = 36 \)
- **Equation of Circle G**: \( (x-3)^2 + y^2 = 9 \)
- **Radius of Circle F (\( R_f \))**: 6
- **Radius of Circle G (\( R_g \))**: 3
#### Integral Expression
The evaluated integral is presented as:
\[
\iint_{D} \sqrt{x^2 + y^2} \, dA = \text{(Calculations Required)}
\]
This problem involves setting the limits of integration based on the given domains of circles \( F \) and \( G \), and evaluating the double integral to find the desired area.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb3cfeff4-8ba6-46a8-98d4-804b4f4f620a%2F00468ae6-c513-41a3-967d-4898d868a97d%2Ff3u0l3_processed.png&w=3840&q=75)
