Find the volume of the solid of revolution formed by rotating about the x--axis the region bounded by the given curves.
f(x)=√x, y=0, x=1, x=4.

16 pi cubic units

Step-by-step explanation:

Given that a region is bounded by

And the region is rotated about x axis.

We can find that here radius would be y value and height would be dx

So volume would be as follows:

If f(x) is rotated about x axis volume

=

cubic units.
