### Volume of a Solid of Revolution

A region bounded by \( f(y) = \sqrt{y} \), \( y = 1 \), \( y = 4 \), and \( x = 0 \) is shown below.

#### Problem
Find the volume of the solid formed by revolving the region about the y-axis.

#### Graph Description
The graph provided shows the function \( f(y) = \sqrt{y} \), along with the vertical lines \( y = 1 \) and \( y = 4 \), and the vertical axis \( x = 0 \). The area of interest is the region enclosed by these boundaries. This region is shaded within the graph to highlight it.

The X and Y axes are labeled, with X ranging from -5 to 5 and Y ranging from -2 to 8.

#### Volume Calculation
The volume \( V \) of the solid formed by revolving this region around the y-axis is one of the following choices:

- ○ \( V = 8 \)
- ○ \( V = 8\pi \)
- ○ \( V = 15\pi \)
- ○ \( V = \frac{15}{2} \pi \)
