The solid lies between planes perpendicular to the x axis at x = −1 and x = 1. The
cross sections perpendicular to the x axis are circular disks whose diameters run from the
parabola y = x
2
to the parabola y = 2 − x
2
. Find the volumes of the solid.

352/105

Step-by-step explanation:

Diameter of the circular disk is

(2−x2)−x2

so that the radius of the disk is the diameter divide by 2

(2−x2−x2)/2.

Integrating V at 1 and -1, we get

V =Z 1−1A dx =Z 1−1π(1 − x2)2

dx = π(x −2/3x3 +1/5x5)1−1

=16/15π

= 352/105

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
