**Problem 9.10** - Determine the moment of inertia of the crosshatched region about the x-axis.

### Description:

The image shows a crosshatched region bounded by two curves, presented on a grid. The x-axis and y-axis have designated coordinates, and the region lies in the first quadrant.

### Key Features:

- **Crosshatched Region:** The region is defined between two curves:
  - \( y = 3x \)
  - \( y = x^2 \)

- **Dimensions:**
  - The horizontal distance from the origin (0,0) to the rightmost point of the region along the x-axis is 4 inches.
  - The vertical distance from the x-axis to the topmost point is 2 inches.

- **Measurements:**
  - The vertical distance from the x-axis to where the line \( y = 3x \) intersects is labeled as 3 inches.
  - The horizontal distance from the y-axis to the point where it intersects with the line \( y = x^2 \) is labeled as 1 inch.

### Graphical Elements:

- The grid provides a reference for scale, with each square unit representing a specified measurement.
- The curves show the boundary of the area in question:
  - \( y = 3x \) is a straight line.
  - \( y = x^2 \) is a parabola opening upwards.

The task is to calculate the moment of inertia of the area between these two curves about the x-axis.
