This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any
points for the skipped part, and you will not be able to come back to the skipped part.
Tutorial Exercise
Find the volume of the solid obtained by rotating the region bounded by the given curves about the x­axis.
y = 7 – 7×2, y = 0
Find the volume V of this solid.
Step 1
When y = 7 – 7×2 is rotated around the x­axis, a vertical strip of width ?x creates a disk.
The radius of this disk is r =
\$\$7-7×2
.
Sketch the region.

Assignment 2
Sketch the solid, and a typical disk or washer.
Step 2
The cross­sectional area of a disk of radius r is A =
\$\$pr2
.
Since our disk has radius r = 7 – 7×2, then the cross­sectional area is
A=
\$\$p(7-7×2)2
.

Step 3
The function y = 7 – 7×2 intersects the x­axis at the following values of x.
x = ­1
(smaller value)
x= 1
(larger value)
Step 4
Now we can say that the volume of the solid created by rotating the shaded area around the x­axis is
x2
V=
1
A(x) dx =
x1
p(7 – 7×2)2 dx .
-1
Step 5
So, the volume of our solid is

p(7 – 7×2)2 dx = p

dx.

This becomes
