00:00:05,000 --> 00:00:06,000
Hello, friends.

2
00:00:06,000 --> 00:00:10,000
Today we discuss about different formulas related to Cone.

3
00:00:11,000 --> 00:00:13,000
As you see over here, I have a cone.

4
00:00:14,000 --> 00:00:22,000
In this case, the height of the cone is small edge radius is smaller and the slant height is l.

5
00:00:22,000 --> 00:00:27,000
So I just take different input variables.

6
00:00:27,000 --> 00:00:39,000
So input is R, second input is H and the third input is slant height.

7
00:00:39,000 --> 00:00:40,000
That is L.

8
00:00:40,000 --> 00:00:45,000
You also create this slant height all using different formulas.

9
00:00:45,000 --> 00:00:48,000
Okay, so let's remove this.

10
00:00:49,000 --> 00:00:52,000
We just create this using formulas.

11
00:00:52,000 --> 00:00:55,000
So input is R and h only.

12
00:00:55,000 --> 00:00:56,000
Okay.

13
00:00:56,000 --> 00:01:05,000
So for the volume we have a formula pi r square h divided by three.

14
00:01:05,000 --> 00:01:05,000
Okay.

15
00:01:05,000 --> 00:01:14,000
So I just go to the compound function pi r square h.

16
00:01:15,000 --> 00:01:18,000
So go to the mathematic function pi.

17
00:01:21,000 --> 00:01:23,000
I got the pi for r square.

18
00:01:23,000 --> 00:01:36,000
I need to square of radius into h pi r square h divided by three.

19
00:01:37,000 --> 00:01:42,000
I need to divide this function, divide by three.

20
00:01:43,000 --> 00:01:51,000
Create a constant that is three and the indicator will indicate the volume.

21
00:01:53,000 --> 00:01:58,000
Okay, so I got the volume of this given

22
00:02:01,000 --> 00:02:01,000
cone.

23
00:02:02,000 --> 00:02:06,000
Let's say radius is three and the height is five.

24
00:02:06,000 --> 00:02:10,000
In that case I got 5.71.

25
00:02:10,000 --> 00:02:11,000
Okay.

26
00:02:11,000 --> 00:02:20,000
So next in this case, I just need to find out the slant height.

27
00:02:20,000 --> 00:02:27,000
We know that the height to find out the slant height, the formula is r square plus H square square

28
00:02:27,000 --> 00:02:27,000
root.

29
00:02:27,000 --> 00:02:33,000
So for that purpose, I need square of H.

30
00:02:34,000 --> 00:02:36,000
It will give me the square of H.

31
00:02:37,000 --> 00:02:39,000
I need to add these functions

32
00:02:42,000 --> 00:02:43,000
over here.

33
00:02:43,000 --> 00:02:47,000
I got the R square and this is my h square.

34
00:02:47,000 --> 00:02:50,000
I need the square root of this given function

35
00:02:53,000 --> 00:02:53,000
over here.

36
00:02:53,000 --> 00:02:54,000
This is the square root.

37
00:02:54,000 --> 00:02:59,000
And I got the slant height over here.

38
00:03:02,000 --> 00:03:05,000
Or you can just put small l over here.

39
00:03:05,000 --> 00:03:10,000
So this is my slant height for the given case.

40
00:03:10,000 --> 00:03:21,000
Let's say just put three into three is nine, five into five is 25.

41
00:03:21,000 --> 00:03:24,000
Let's check what is the slant height.

42
00:03:24,000 --> 00:03:27,000
It is 5.8.

43
00:03:27,000 --> 00:03:28,000
Okay.

44
00:03:28,000 --> 00:03:43,000
In this case, or let's say it is four, as you see three, four, five combination is there in Pythagoras.

45
00:03:43,000 --> 00:03:48,000
So I got five as a slant height over here.

46
00:03:48,000 --> 00:03:52,000
So my formula is okay, code is running properly.

47
00:03:52,000 --> 00:03:59,000
So now next formula is to find out the surface area.

48
00:04:00,000 --> 00:04:09,000
So the surface area is pi r into r plus h square plus r square square root.

49
00:04:09,000 --> 00:04:17,000
So in this given case, I already created this formula square root of x square plus r square.

50
00:04:17,000 --> 00:04:22,000
I just need to add R into it.

51
00:04:25,000 --> 00:04:29,000
So this is my r square plus h square.

52
00:04:29,000 --> 00:04:30,000
Whole square root.

53
00:04:30,000 --> 00:04:32,000
I need to add R into it.

54
00:04:32,000 --> 00:04:40,000
So this is my this inside one function r plus square root of x square plus r square.

55
00:04:40,000 --> 00:04:47,000
Now I need to multiply it with pi r so for that purpose I just take compound function.

56
00:04:47,000 --> 00:04:53,000
So this function is multiplied with pi into r.

57
00:04:54,000 --> 00:04:56,000
So this is my r over here.

58
00:04:57,000 --> 00:05:04,000
I just change the mode to multiply and over here it will give me the final.

59
00:05:04,000 --> 00:05:05,000
Output.

60
00:05:05,000 --> 00:05:11,000
That is my right circular cone surface area.

61
00:05:12,000 --> 00:05:18,000
This is my surface area.

62
00:05:18,000 --> 00:05:19,000
Okay.

63
00:05:19,000 --> 00:05:26,000
So you can run it and you just find out the surface area.

64
00:05:26,000 --> 00:05:29,000
Okay, so let's check for the another formula.

65
00:05:30,000 --> 00:05:39,000
So if you want to find out lateral surface, as you see, the lateral surface is denoted by L over here

66
00:05:39,000 --> 00:05:44,000
and it is pi r into S square plus r square.

67
00:05:44,000 --> 00:05:52,000
So as we already know that this is my s square r square square root, so I need to multiply it with

68
00:05:52,000 --> 00:06:10,000
pi into r so this is my input pi into r, so over here this will give me the lateral surface.

69
00:06:17,000 --> 00:06:18,000
Just run it.

70
00:06:24,000 --> 00:06:26,000
So over here, this is the lateral surface.

71
00:06:26,000 --> 00:06:35,000
So this is how you can find out different formulas or different area volume, lateral surface, slant,

72
00:06:35,000 --> 00:06:37,000
height of the given cone.

73
00:06:37,000 --> 00:06:38,000
In LabVIEW.
