Tutorial Exercise
Set up and evaluate the integral that gives the volume of the solid formed by revolving the region about the x-axis.
Step 1
From the figure consider the representative rectangle. The radlus of the solid of revolution obtained by re volving the rectangle about the X-axis is
R(x) = y = 9 - , 2.
To find the volume of a solid of revolution with the disk disk method, use the horizontal axis of revolution.
(R(X)1? dx.
Volume = V = 1

Step 2
So, the volume of the solid of revolution is
Volume = V=
(9 - x-)2 dx.
To find the volume, integrate from x = |
to x = 3.
