00:00:00.610 --> 00:00:03.690 A:middle L:90%
we know the formula for this for volume is gonna
2
00:00:03.690 --> 00:00:06.519 A:middle L:90%
be two pi times the intro from our bounds A
3
00:00:06.519 --> 00:00:10.300 A:middle L:90%
to B zero pie Times Radius, which is axe
4
00:00:10.300 --> 00:00:13.349 A:middle L:90%
minus negative one, which is X plus one times
5
00:00:13.349 --> 00:00:16.280 A:middle L:90%
height, which is X cubed sign of ex,
6
00:00:16.289 --> 00:00:18.850 A:middle L:90%
both of which were given in the original problem.
7
00:00:19.239 --> 00:00:22.379 A:middle L:90%
Now what we know is that we can type this
8
00:00:22.390 --> 00:00:24.960 A:middle L:90%
into our calculator cause it's saying computer generate systems.
9
00:00:24.960 --> 00:00:29.609 A:middle L:90%
This means Wolfram Alpha calculator, Dez most math way
10
00:00:29.620 --> 00:00:31.600 A:middle L:90%
. Any sort of computer generated system. You could
11
00:00:31.600 --> 00:00:33.880 A:middle L:90%
plug this end too, and you will end up
12
00:00:33.880 --> 00:00:37.850 A:middle L:90%
with exact value, which again means no decimal places
13
00:00:37.939 --> 00:00:41.299 A:middle L:90%
. No estimation, no rounding. What it means
14
00:00:41.299 --> 00:00:44.329 A:middle L:90%
is that we direct pie out is the symbol pi
15
00:00:44.530 --> 00:00:47.500 A:middle L:90%
. That's what exact means again. 3.14 is not
16
00:00:47.500 --> 00:00:49.850 A:middle L:90%
exact. Exact is only exact when we write out
17
00:00:49.859 --> 00:00:52.820 A:middle L:90%
exactly like pie. So using Pew triggering system,
18
00:00:52.829 --> 00:00:54.149 A:middle L:90%
we would end up with us
