Step 1 :Consider the solid obtained by rotating the region bounded by the given curves about the specified line. The curves are \(y=\sqrt{x-1}\), \(y=0\), and \(x=4\); and the rotation is about the x-axis.
Step 2 :Set up an integral that can be used to determine the volume \(V\) of the solid. The volume of such a solid can be found using the disk method, which involves integrating the area of cross-sectional disks.
Step 3 :The area of each disk is given by \(\pi r^2\), where \(r\) is the distance from the disk to the axis of rotation. In this case, the radius is given by the function \(y=\sqrt{x-1}\), so the area of each disk is \(\pi (\sqrt{x-1})^2 = \pi (x-1)\).
Step 4 :The volume is then found by integrating this area from the leftmost to the rightmost x-values of the region, which are \(x=1\) and \(x=4\) respectively. Therefore, the integral that gives the volume of the solid is \(V = \int_{1}^{4} \pi (x-1) dx\).
Step 5 :Finally, the integral can be calculated to find the volume of the solid. The final answer is \(V = \boxed{\frac{9\pi}{2}}\).
