Question
**Find the Volume of the Solid Generated by Rotation**

**Problem 3:**  
Calculate the volume of the solid generated when the area between the two curves is rotated about the specified line of revolution. 

**Instructions:**  
- Evaluate the integral for this problem.  
- Clearly indicate the method used and label the radius/radii.

**Graphs/Curves:**

1. **Equations of the Curves:**
   - \( x = y^2 \)
   - \( x = 1 - y^2 \)

2. **Intersection Points:**
   - The curves intersect at the points \( \left(\frac{1}{2}, \frac{\sqrt{2}}{2}\right) \) and \( \left(\frac{1}{2}, -\frac{\sqrt{2}}{2}\right) \).

3. **Line of Revolution (LOR):**
   - The area between the curves is rotated about the line \( y = -1 \).

4. **Graph Description:**
   - The graph shows two curves intersecting symmetrically around the \( y \)-axis.
   - The curve \( x = y^2 \) is colored black, and the curve \( x = 1 - y^2 \) is colored red.
   - The \( y \)-axis is vertical, and the \( x \)-axis is horizontal.
   - The line of revolution \( y = -1 \) is depicted as a dashed horizontal line below the x-axis. 

**Objective:**  
Determine the volume of the solid formed by revolving the region enclosed by the curves about the line \( y = -1 \). Use the disk, washer, or shell method as appropriate and clearly label all components.
