00:00:00.840 --> 00:00:02.940 A:middle L:90%
okay, As we can see from the diagram,
2
00:00:02.940 --> 00:00:06.570 A:middle L:90%
we conceive that we're integrating along the parallel access to
3
00:00:06.570 --> 00:00:09.230 A:middle L:90%
the axis of rotation. We know we're looking at
4
00:00:09.230 --> 00:00:11.580 A:middle L:90%
the line y equals acts, which is just like
5
00:00:11.580 --> 00:00:16.059 A:middle L:90%
this on Reichel's axe Radius is our equals X.
6
00:00:16.140 --> 00:00:18.339 A:middle L:90%
For this, we can use the disc method between
7
00:00:18.350 --> 00:00:20.190 A:middle L:90%
you have pie on the outside. It's a constant
8
00:00:20.190 --> 00:00:24.250 A:middle L:90%
from 01 Those are limits of integration. X squared
9
00:00:24.359 --> 00:00:30.120 A:middle L:90%
. Jax, right? The integral using the power
10
00:00:30.120 --> 00:00:32.420 A:middle L:90%
rule increased the expert by one divide by the new
11
00:00:32.420 --> 00:00:36.549 A:middle L:90%
exponents. Now we're at the point we can plug
12
00:00:36.549 --> 00:00:41.469 A:middle L:90%
in our values and we end up with our solution
13
--> A:middle L:90%
.
