Step-by-step explanation:
Please refer to the graph below.
So, we want to find the volume of the solid generated by revolving the green area about the x-axis.
We can use the disk method. The disk method is given by:
Where R(x) is the radius or height of the representative rectangle.
We are integrating from <em>x</em> = 0 to <em>x</em> = ln(π). The height of a representative rectangle is given by <em>y. </em>Therefore, the volume is:
Simplify:
Approximate. So, the volume of the generated solid is:
The solid is shown in the second figure.
