Question

For the cross section in problem 1 (which is also shown below), you are asked to determine the moment of inertia about x axis or Ix. Show all the necessary steps.  

### Problem Statement:

**For the cross section in problem 1 (which is also shown below), you are asked to determine the moment of inertia about the x-axis or \( I_x \). Show all the necessary steps.**

### Diagram Explanation:

The image below is a diagram of a cross-sectional area, labeled according to the x and y axes.

- The cross section consists of a quarter-circle with a radius of 2 inches centered at the origin, along with a circular hole of radius 1 inch.
- The quarter-circle extends from the origin (0,0) to 2 inches along both the x and y axes.
- The center of the circular hole is located at coordinates (0.5, 0.5).
- The dimensions indicated in the diagram include:
  - Horizontal length along the x-axis: 4 inches (total width)
  - Vertical length along the y-axis: 2 inches (height of the quarter-circle section)

**Key Points:**

1. Quarter-circle extends 2 inches along both axes.
2. Circular hole has a radius of 1 inch and is centered 0.5 inches away from both the x and y axes.
3. The coordinate system is marked with the x-axis being horizontal and the y-axis being vertical.

### Objective:

**Determine the moment of inertia about the x-axis ( \( I_x \) ). Show all necessary calculation steps including breaking down the geometry and applying relevant formulas.**
