### Problem Description

1. A solid insulating cylinder with positive uniform volume charge density \( \rho \) and radius \( a \), is surrounded by a thin-walled insulating cylindrical shell with negative uniform surface charge density \( -\sigma \) and radius \( b \). The two cylinders are coaxial (share the same central axis) and both have a length \( L \). Use the quantities given and a cylindrical Gaussian surface.

### Diagram

The diagram illustrates a cross-sectional view of the described setup:
- A solid inner cylinder with a labeled charge density \( \rho \).
- An outer cylindrical shell labeled with charge density \( -\sigma \).
- The inner cylinder is represented by a solid circle with radius \( a \).
- The outer cylindrical shell is represented by a dashed circle with radius \( b \).

### Questions

1. Write an expression for the charge enclosed within region \( r < a \).
2. Write an expression for the electric field within the region \( r < a \).
3. Write an expression for the charge enclosed within the region \( a < r < b \).
4. Write an expression for the electric field within the region \( a < r < b \).
5. Write an expression for the charge enclosed within the region \( r > b \).
