Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line. y = ln(3x),
denis23 [38]

Using the disk method, the volume is obtained with the integral

\displaystyle\pi\int_{y=1}^{y=5}\left(\frac{e^y}3\right)^2\,\mathrm dy=\frac\pi9\int_1^5e^{2y}\,\mathrm dy

The radius of each disk is given by the horizontal distance from the axis of revolution, x=0, to the logarithmic curve which we can write as a x(y):

y=\ln(3x)\implies e^y=e^{\ln3x}=3x\implies x=\dfrac{e^y}3

Then the volume of one such disk is \pi x(y)^2.

The volume of the entire solid would be

\displaystyle\frac\pi9\int_1^5e^{2y}\,\mathrm dy=\frac\pi{18}\int_1^52e^{2y}\,\mathrm dy=\frac\pi{18}\int_1^5e^{2y}\,\mathrm d(2y)

=\dfrac\pi{18}\left(e^{10}-e^2\right)
