Sir class 9 math syllabus bata dijiye
Awaj kam ha video ma
Sir dome Wale question mein area ka apne 4 pie r² likha hai lekin vo to 2pie r² hon chaiya tha because of the csa
sir one suggestion for u that you should dont do the step to multiply but u can tell the final answer so that we should know that we have done the answers correctly or the answer is wrong so plese take note . altho u are very good teache . thank u😊😊
2024 wale attendance do 🤚
Everyone wants a teacher like him. But. Every teacher needs a student who can study like we do in TH-cam 💀

Diameter of MOON=2r
Radius of MOON =r
Radius of EARTH = 4r.
Ratio of their surface areas= (4*22\7*r*r)\(4*22\7*r.*r.)
=r*r
.*r.
=r*r\4r*4r
=1\16
=1;16
Dude I think r*r = r killing square
@@EVESH_JAINno bro his sol is correct check it from back side of ncert book..
16:42 sir radius was 7/2 but you wrote 7/4.
Otherwise the lesson was awesome and it helped me alot. Because of you sir I scored 49marks out of 50. Thanks a lot.
Science and fun teachers are amazing but I think that they should smile a bit during there lectures 💀🙇♀️
1:55
ME SMILING WHEN MY CLASS TEACHER IS COMPLAINING MY PARENTS ABOUT MY BEHAVIOUR 😂⚰️
16:30 there is mistake students its 7/2 value of radius we have to put not 7/4
Yes
right
sir kA mAAn divert ho gAyA
please work on audibility
Sir your maths calculation at √343 is wrong
And is √343 = 18.52 not 16.6
Sir aap offline me kitni fees lete ho
5000
1:16
49:01
The radius will be 18.5 approx
( Square root of 343 is 18.520.. something)
Just write 7√7, we don't even need the individual value. We just need r². 🐺
I liked my own comment😊
Me tooo 😂@@PawanVerma-lt7rb
11:18
Ans 1437.3 cm³
My answer is 142.038 cm3
Jiska pehle question ka answer 3845.4416 aya hai vo like karo 😊
Sir the session was very awesome but to recheck my answers i wanted to ask that are all the answers for the questions of spheres and hemispheres in the value of non terminating recurring or non terminating non recurring (except for some)??
Plz answer sir 🤩🤩
13:00
sir apna jo padhya sab acha sa samajh aa gya lekin bhot dikat hui kyunki apki voice bhot kam aar ithi
The ratio of surface of their surface area is 1 : 16
21:06 here sir 2pier^2 will be used
Sir apto 1 hour ma 13 sum karha ho ,to hum 3 hours ma 😢😅42 sum kasya karaga
Dukh hi hi dukh ha
48:56 sir 16.6 ka square 275.56 hota hai aur 18.520 ka square 342.9904 hota hai to apne 16.6 leka hai apko 18.520 lek na tha
1:16
37:40 answer is 1:16 ratio
1:03:15 sir I have doubt please explain it
1 saal hogya bhai 😂😂
😂
Sir please volume increase
Sir volume wala answer halat hai jisme ap question hai surface area is 154 hai wo wala 7/2cm radius to app 7/4cm likha ho
Wow sir ....app ne bhut achaa padaya 😊just woww
Sir you like Ashu sir 😊
Abe unke hi bhai h
Sir thoda sound shi karo awaj sunai ni aa rhi
At the end ,topi faad hi di...😂😂

Which school
Sarkari hoga iska
18:22 i think i heard morse code 💀💀
Best of luck of exam
34:50 question answer is
T.S.A of hemisphere =4158 cm²
C.S.A of hemisphere =2772 cm²
😮😂❤😅😢
Thank you so much sir for your support to explain whole chapter tomorrow is my maths exam thanks 🙏🙏❤
Answer Of Homework is 1:16
Thnx For Explanation Sirrr
16:44 sir you used r as 7/4 instead of 7/2
Haa

bhai ho kya rha ha 20:37 me sir sphere k csa ka forumula dal rhe ha bhai!! mai yha 3pi rsq. k formula se kr rhe hu aur ye!!! like wt the helll
Sahi bola
Sir please class10 ka surface areas and volumes karwa do kuch nahi samajh aa raha please sir🥺🥺🥺🥺
सर आप बिल्कुल आशु सर जैसे हों बस थोड़ा सा ही फर्क हैं 🥳👏🙏🙂🙂🙂🥳🙏
आप आशु सर के भाई हैं क्या सर 😆😊😊😊
Yes
Sir the answer will be 1:16
Sir u can directly substitute value of rsqare =343 in equation 1/3 pie r square h . No need to calculate the value of under root 342😂
1:16 hai sir is ka answer
Sir 16:42 pe shouldn't it be 7/2 since r=7/2
Wohi toh
Iron
Rao sahab rao sahab hoori shahar main
The answer is 1:16
R square is 343
1/3×22/7×343×21
=7546
Square root nekalne ki jarurat nahi thi
Excited ....for lecture ❣️
Better than un academy
Nice explanation but audio is bit slow
Toh Bhai Speed bada le
THANKS SIR aap to keher macha rahe ho😍😃
Next chapter please
Sir please make a video on maths paper presentation and also tell in brief that in which chapter we have to write given and to find please sir
48:55
r = 18.5 approx
Sir i love your teaching ❤
Sir aapnei ek ques mei formula galat likha hain in dome
I noticed at 20:45
Inka koi bhai hh kya
Such aGreat explaination sir❤😊🎉
Sir 50:03 the answer will be 8 because diameter is there
Sir hindi medium ke bachcho ke liye kuchh kariye Ashu sir is great
Ashu science his wife SSt ushank maths his wife English teach😮
Sir. I need now Triangle
Phele mujhe laga ashu sir kab se maths padhane lage 😂😂😂
37:40 sir the answer is 1:16
Sir I like your teaching and your style
But ,in today's lecture your voice is tooo low 😅😅
Please upload the video of congruence of triangles it is very difficult for me to understand triangles
Easy
@@nitishsingh6887 yea! you are just like me. its pretty easy
many classmates in my class thinks that geometry is hard especially triangles
its been months now@@BrainStorm2-r6v
Koi ye bta do radius kese nikalte hai
Agar diameter Diye hain to uska half karne per radius aata hai
@@nvoditmishra653 bhot bhot thanku ❤️
Jaruri nahi hai ki yahi step use ho
@@XYZgames2010hmm koi or hai to bta do pls
Bro par wo question pe depand kerta hai agar na radius de rekha hai na diameter to question apko circle ya phir sphere ka ek bharamastr dega area Jise formula mai put Kane se radius niklti hai bhot uljha hua step hai na
Hello sir
Sir before u tell that your brother of ashu sir I new that you both are brother's
Sir we can take directly radius in square.. Because in formula there is r square.. We can take it as it is.
Sir apne que 4 of shere and hemisphere sir when u put the value of radius on finding volume u mistakely wrote 7/4 but its actually 7/2 BUT anyway u are good teacher
Sir sound ache se nahi aata hai 😢
Light Bulb
sir aap agr meje 10 me math padha do gay to mai top karunga
💀💀☠☠☠☠☠🤑🤑🤑🤑🤑🤑🤑🤫🤫🤫🤫
Sir you have done mistake 16:20 there will be 7/2 instead of 7/4
3105.7 is the answer for second one
16:24
Sir lekin radius toh 7/2 hai 😶
20:31 sir aapne surface area of hemisphere galat liya hai it is not 4πr² it is 2πr²
Hlo sir,
Sir I had watched video from 00:00 to 38:01.
Is it only video of sphere & hemisphere concept and question?
Amazing🙃🙃🙃
Ashu sir - physics teacher
His wife- S.St teacher
And aap ushank sir - maths teacher
sir your lectures are very very good but sir can you speak little louder because we cant hear properly sorry
Sir i got ratio 16:1
Sir in cone's second question 343 root will be 18.5 but you have wrote 16.6 sir.
why to find the square root . we need r2 only
Sir aapne jo question karaye vahi aaye 😅 ❤ thanks sir 🎉🎉
Is this class 10th surface area and volume or class 9th??
Class 9
