Exams are near😢
Nothing is clear😂
Pressure is peer😮
We all are in teer😊
Nothing is going to be cheer
But
Not to be fear 😨
When ritik sir is here 😎

Sol-
The radius of 1.5m
The height is 7m
We have to find volume because in volume we can find the liter of milk.
=The volume of cylinder=πr²h
=²²/⁷ × 1.5 × 1.5 × 7
=49.5m³
{ 1m³=1000 litre }
So, 49.5m³ =49500liter.
Thank you

[GAMER-reep]

Even after paying fees to the teachers at school we don't understand any concepts, but here for free u r giving us a quality education thank u

This is the first time i am enjoying a maths class 😭😭🥺

[ophacker]

Sir, , the question at time of video(1:24:12), , , answer of that is 49.50 m³ but what is that (in litres, etc) or which unit we have to write in exam...

[raghavgamer]

26:16 Thank you sir 🙏. ❤. ❤. ❤.

[sararazaparveen]

The amount of efforts they put to make you understand things 💖

In a cylinder both circle are equal then we can say that it is a cylinder

[ClassyRishav..]

Q.2, The Volume of Milk In The tank Is 49.5m3

Volume of Cylinder = π×r×r×h
=22/7×1.5×1.5×7 = 99m³/2 = 49.5m³

[dhaarakalwani]

if I had a math teacher like this I would go to school with interest every day

[emoxcorez]

10:29 two circular surfaces are identical but in this figure upper circular surface and lower circular surface is not same in size 😊

[ShakirZahoor-nfsz]

Your way of understanding a weak student like me is outstanding 😢 . May our god will shower his blessings on u

[hgamez]

10:24 because its circular faces are not identical

[LaughingLiterate]

I'm not sure but what I think the answer of that question is that...

It is incorrect to call that shape a cylinder because it's two faces are not identical...
I don't know if I'm correct or not and if I'm incorrect please correct me ❤❤❤

[strokesznn]

Fr I scored veryy good and high marks because of Ritik sir the amount of efforts he put to make us understand the particular thing and how he even entertain us. Hat's off to him. He is really an amazing teacher. Because of him I got interested in doing maths. Frrr Hat's of to him. He will always be my favorite teacher>>>

Given, r=1.5
h (length) = 7

Volume of cylinder =πr²h
= 22/7 × 1.5 × 1.5 × 7
= 99/2 m³

1m³ = 1000L
2m³ = 2×1000L = 2000L
99/2m³ = 99/2 × 1000L = 49500L

Thus, 49500L milk can be stored in the milk tank .

[shouryasrivastavaa]

48:43 bhai sir ne kaha " mera to kata hi hua hai"

[MohitVashisth]

1:24:40

Sir volume of cylinder tank is 49.5m³
Also the volume of milk is 49.5m³

Ans thank you for your perfect teachings
We are proud of we can study without paying feee 🤣🤣😄🤣😝😀

[Weird_wonderings]

10:42 Because two circular surfaces should be IDENTICAL.
THANKS FOR EXPLAINING IN SUCH A GOOD WAY.💖💖👌👌👌👍👍👍👍
