### Figure 8.14

3. 
a. Write a Riemann sum approximating the area of the region in Figure 8.15, using horizontal strips as shown.

b. Evaluate the corresponding integral.

### Description of Figure 8.15

The diagram shows a graph with the curve \( y = x^2 \). The graph includes the following features:

- The vertical axis is labeled \( y \) and has a range marked up to 9.
- The horizontal axis is labeled \( x \) with a limit marked at \( x = 3 \).
- A horizontal strip of height \(\Delta y\) is shown between the curve and the line \( y = 9 \).
- The graphical area of interest is located above the x-axis and below the curve \( y = x^2 \), extending from \( x = 0 \) to \( x = 3 \) and \( y = 0 \) to \( y = 9 \).

The task involves using horizontal slices (strips) to approximate the area under the curve \( y = x^2 \) from \( x = 0 \) to \( x = 3 \) and then calculating the exact area using integration.
