Compute the volume of the solid of revolution generated by f(x) = x^(1/4)

Sketch the graph and compute the volume of the solid of revolution generated by:

    \[ f(x) = x^{1/4}, \qquad \text{on} \qquad 0 \leq x \leq 1. \]


The sketch of the ordinate set of f(x) = x^{1/4} on [0,1] is as follows:

We then compute the volume of the solid of revolution.

    \[  V = \int_0^1 \pi x^{1/2} \, dx = \pi \left. \frac{2x^{3/2}}{3} \right|_0^1 = \frac{2 \pi}{3}. \]
