**Finding the Volume of a Solid of Revolution**

Consider the problem of finding the volume of a solid obtained when the region under the curve \( y = \sqrt{x} \) over the interval \([1, 4]\) is revolved around the x-axis.

To compute this volume, we use the formula for the volume \( V \) of a solid obtained by revolving a region under the curve \( y = f(x) \) from \( x = a \) to \( x = b \) around the x-axis:

\[ V = \int_{a}^{b} \pi [f(x)]^2 \, dx \]

In this specific problem:
* \( f(x) = \sqrt{x} \)
* The interval \([a, b] = [1, 4]\).

Substituting these into the volume formula, we get:

\[ V = \int_{1}^{4} \pi (\sqrt{x})^2 \, dx \]

Here, \( (\sqrt{x})^2 = x \), so the integral simplifies to:

\[ V = \int_{1}^{4} \pi x \, dx \]

This integral can be evaluated to find the volume of the solid of revolution.
