00:00:00.040 --> 00:00:02.430 A:middle L:90%
he was like he asked me for a dollar were
2
00:00:02.430 --> 00:00:05.190 A:middle L:90%
given a figure in the figure. There's a region
3
00:00:05.190 --> 00:00:07.089 A:middle L:90%
of the line and we're asked to find the volume
4
00:00:07.089 --> 00:00:10.310 A:middle L:90%
generated by rotating this region about this line. The
5
00:00:11.859 --> 00:00:17.500 A:middle L:90%
region is right. Our two rotating this about the
6
00:00:17.500 --> 00:00:20.670 A:middle L:90%
line. BC. What I will give you some
7
00:00:20.670 --> 00:00:25.469 A:middle L:90%
advice you know? Now do you know what pheromones
8
00:00:25.469 --> 00:00:29.750 A:middle L:90%
are? I was like yeah. So looking at
9
00:00:29.750 --> 00:00:33.240 A:middle L:90%
her figure, It sounded above by the line.
10
00:00:33.240 --> 00:00:37.320 A:middle L:90%
Why it was one and bounded on the right ID
11
00:00:37.320 --> 00:00:40.350 A:middle L:90%
occurred. Why equals the fourth root of X.
12
00:00:41.039 --> 00:00:45.210 A:middle L:90%
And left by the line x equals zero. Now
13
00:00:45.210 --> 00:00:49.649 A:middle L:90%
the line you see this is the horizontal line.
14
00:00:50.140 --> 00:00:56.289 A:middle L:90%
Why it goes one three four. Looking at the
15
00:00:56.299 --> 00:01:00.170 A:middle L:90%
figure, we see that we get a gift type
16
00:01:00.170 --> 00:01:03.119 A:middle L:90%
solid. So that will use the best method.
17
00:01:03.189 --> 00:01:06.260 A:middle L:90%
Therefore we need to find the radius of our disk
18
00:01:06.939 --> 00:01:10.069 A:middle L:90%
. Ask jake. Well this is going to be
19
00:01:10.829 --> 00:01:15.530 A:middle L:90%
y equals 1-5 equals you fourth root of X
20
00:01:15.540 --> 00:01:21.150 A:middle L:90%
. Um uh It's bad. instead of volume.
21
00:01:21.159 --> 00:01:25.219 A:middle L:90%
By the get method is high times and a girl
22
00:01:25.219 --> 00:01:34.799 A:middle L:90%
from X equals zero two x equals one of the
23
00:01:34.799 --> 00:01:38.950 A:middle L:90%
radius, one minus the fourth root of x squared
24
00:01:38.739 --> 00:01:42.159 A:middle L:90%
. Yes, no, nothing you can say.
25
00:01:42.879 --> 00:01:47.950 A:middle L:90%
And if you evaluate this in the role should get
26
00:01:49.040 --> 00:01:53.489 A:middle L:90%
hi over 15.
