1
00:00:00,560 --> 00:00:07,880
Let's do this question, a spirit of radius are as the same volume as that of a cone with a circular

2
00:00:07,880 --> 00:00:11,450
base of radius to find the height of the cone.

3
00:00:11,630 --> 00:00:12,080
All right.

4
00:00:12,080 --> 00:00:15,300
Pause the video, give it a try, and then let's do it together.

5
00:00:15,560 --> 00:00:16,010
All right.

6
00:00:16,010 --> 00:00:16,470
We're back.

7
00:00:16,490 --> 00:00:17,470
Let's do it together.

8
00:00:17,660 --> 00:00:21,710
Now, the volume of a spear has given us four by three by our cube.

9
00:00:21,720 --> 00:00:22,040
Right.

10
00:00:22,220 --> 00:00:27,020
And the volume of a cone is given us one by three by our square inch.

11
00:00:27,180 --> 00:00:29,720
But in this case, the radius is to our right.

12
00:00:29,900 --> 00:00:31,610
So let's take it as two are.

13
00:00:31,610 --> 00:00:36,710
Therefore, the volume of the cone will be one by three by Endou to our square.

14
00:00:36,710 --> 00:00:37,510
It's right.

15
00:00:37,670 --> 00:00:40,220
And over here it's given that these two are equal.

16
00:00:40,400 --> 00:00:42,920
So let's equate them so you get four by three.

17
00:00:42,920 --> 00:00:45,110
Bay'ah Cube is equal to one by three.

18
00:00:45,110 --> 00:00:48,170
Bite into four square into X.

19
00:00:48,170 --> 00:00:48,480
Right.

20
00:00:48,620 --> 00:00:50,570
Now let's simplify it over here.

21
00:00:50,570 --> 00:00:52,270
These three and this three gets canceled.

22
00:00:52,590 --> 00:00:53,020
All right.

23
00:00:53,030 --> 00:00:56,150
This four and this four gets canceled.

24
00:00:56,450 --> 00:00:58,450
This by and this by gets canceled.

25
00:00:58,700 --> 00:01:02,330
So you're left with our cube is equal to our square into each.

26
00:01:03,300 --> 00:01:07,050
Right, or you get R is equal to it.

27
00:01:07,260 --> 00:01:12,510
That is the height has to be equal to the radius and that is option C over here.
