Are sr namaskar g, r theek hai d v theek hai but 22 l/ 7 Kahan se Aya hai lafra toh pai ka hai or jisne pai ko dhooda sr Arya Bhatt g ka naam nahin Lena tha Kia bhaiya Ji, bhaiya Ji ye quantum me batao sr Bhatt g ke dimag me kaise aya thanks 🙏🙏👍
This formula can also be derived through Calculus by integrating the circle equation
x^+y^=a^
with limits -a to +a
and finding the area under curve.
Bro this the actual method the method in the video is good but the are to many approximation which is quite not useful so using calculus is the real method so hats off to your approach
Well l had studied from an english medium school and l am in 8 standard so. l found a little difficulty to understand the terms in Hindi but no problem it was a very good explanation. ❣️ Sab kuch bahut achhe se samjh me aagaya......✨🌈
Sar aapko bahut bahut thank you Aise Bhi Karke Koi Hamen Sikhaya Nahin aap Jaise Sikhaya Jaisa ke mera dimag Mein baith Gaya ka bhi hat Jaega Nahin
Nice explanation, you are an asset for India.
Thanks very much Sir for valuable knowledge.
You are GENIUS... Easy way of teaching.. Hope even Toughest chapters will be taught easily.... God bless you
राष्ट्रीय और अन्तर्राष्ट्रीय गणित दिवस कब मनाया जाता है? यह किस के सम्मान में मनाया जाता है? रामानुजन संख्या क्या है? विस्तार से समझायें |
सर आपका गणित फेवरेट विषय है मेरा तो है
@@ajeetkumarverma9923 सर, सही कहा आपने |
@@ajeetkumarverma9923 सर आप अपनी परिचय दीजिये, आप की comment थी मेरे पिछले प्रश्न पर , आज भी है | मैं तो आपने बारे में what is mathematics वाली video में बता चुका हूँ |
मैं u.p के बलिया जिले से हुँ
@@ajeetkumarverma9923 यह प्रश्न कैसा लगा, यह प्रश्न भी पुछता रहूंगा जब तक उत्तर नहीं देगा | अभी कुछ दिन इंतजार कर रहा हूँ |
Yeah it could also me achieved using approach of Calculus . Consider a circle of " R " (radius) and choose a differentiatial element at a distance r from centre such that it's thickness is dr (using symmetry) and find its area which 2πr(dr) and then integrate from 0 to R.
एक जमींदार ने 9 गाय 3ब्राह्मणों को इस प्रकार दान दी कि Aको24%, Bको18%तथाCको12% मिले,सवाल हल(गणना) करके बताओ किसको कितनी मिलीं?
A ब्राह्मण को 2 गाय
B ब्राह्मण को 2 गाय
C ब्राह्मण को 1 गाय मिलेगा |
thank you sir I understood very well
Guys just use calculus we know eq of circle y=√(a²-x²)
Now for area integrate the function from -a to a and multiply by factor of 2 which ultimately reach to the result A=πa² where a is radius of circle
Sir very good
Sir please aap class fifth 5 k maths subject ka bhi video banaya kijiye. Please sir little children should also understand maths in such a way that you are teaching so that their base must be strong. Thank you.
Remarkable observations..my quest solved.
I never learned such easy way to understand this formula. Your are great sir.
Very well done!
Thanks
Super explain 💕
Thank you sir 👏👏👏
App genius ho sir 👏
Step 1. Draw a square, 2 diagonals and inscribe a circle in the square. Thereby side and diameter will be the same
Step 2 : Subtract 2 diagonals from the perimeter of square
Step3. Divide step2 with 8
Step4. Add 3 times of the side. to Step 3
At the end we get the EXACT circumference of the inscribed circle.
Happy Happy super sir ji 💝💝💝 Jehanabad
Bahut bahut dhanyawad sir 🙏🙏🙏🙏👍🏻👍🏻❤️
Superb explaination Thanks a lot
Sar aap ka bahut bahut shukrya
बहुत बहुत धन्यवाद सर ।आज मुझे वॄत के क्षेत्रफल का concept पुरा clear हो गया । Thank you Sir.
Wow rangit sir
Bahut bahut dhanyawad sir Aaj pahli bar Jo khoj rhe the ooo sikhne ko Mila mujhe bahut Janne Ka Maan tha Ki ye forma bana Kaise Aaj Sikh Gaye sir Ji bahut bahut danyawad
Sir mujhe aa gya me maths me bohot kamjor hi thank u ❤❤❤❤👌👍🙏🙏🙏🙏
Aap to kamal kar diye
Bhut achchha samjhaya apne.hmesa yad rhega ki ,why the area of circle is pie x r.r.
Bahut video khojne ke baad mila❤❤❤❤
Sir you are real hardworking person thanku so much
Accilent geometry I am a student of science so wonderful teaching sir, thanks for the topic sir....
You are most welcome

I like you the most among all math's teachers. Sir,area of a circle can also be derived by integration?
Sir gajab explanation
Thanks for some good general knowledge
Are you Best teacher
School me aisa to nahi sikhaya tha. Best one.
Great sir😁😊
Awesome Sir ji! Can you also explain why the ratio bewteen circumference to diameter is always 22/7? Keya iska koi thos proof hain?
22/7 isn't a actual value of π. The real value of Pi still isn't discovered yet. So, we take 22/7 as pi because it's one of the closest number to pie and it's easy to divide (like 9.999 is closest to 10 same with 22/7 and pi)
Watch it from 7:41 If you already know how to calculate the area of a circle

Very intelligent and very interesting. Logically made understand.
वाकई आप जीनियस हैं.
Thanks sir bhut achha
thanks bro
I want to ask one question that is-A and B can complete a work in 6 days, only B can finish in 16 days so in how many days it takes A to complete that work?
Answer kyaa h
Lund jaisa question ha bosdike 48/5 hoga
(16×6) ÷(-16-6)= 96÷10 =9.6

हैक्टेयर, एकड़, बीघा, बिस्सा, बिस्वांसी आदि में तो स्क्वायर नही लगता।
Bhai khet cylinder size nahi
Hota aur waha , two pai r square measurement nahi hota
ये सब क्षेत्रफल के मात्रक हैं इसलिए वर्ग नहीं लगता, अगर हेक्टेयर, एकड आदि लंबाई का मात्रक होता तो वर्ग लगता इनके पहले या बाद में
@@ihmapraveen3361 अरे भाई साहब यें सब मुझे पता है। मैंने उस बात की तरफ संकेत दिया था जहां एक जगह मास्टर जी कह रहे है कि जहां क्षेत्रफल होगा वहां स्क्वायर जरूर आएगा। मै केवल ये बताना चाहता था कि ऐसा कोई नियम नहीं है।
Hectare or acre is the unit of area.for example we write 10,000 m² =1hactare.
@@hashtag_komal_chaudhary अबे पता है, पहले पूरी बात तो समझ लें
πr^2 को समझा ने के लिए आप ने बड़ी आसानी से परिधि = 2πर ले लिया। ये तो बताईये परिधि =2πr कैसे हुआ!
Sir you teach on my school in nepal you are math god❤❤

Your thinkness is very nice
Sir AAP ko yese knowledge kaha se prapat Karte ho plz tell me sir
Aap kaise sabit kar sakte ho ki ,πr ko r se multiply krne se πr ki power 2 ayega.
Sir ma aapka bohat bada fan hoon
Aaj ham master bana, thank you sir
Very good explanation bro
Thank you sir

Very good. Thank you sir.

Sir, second method me length 2πr/2 kyuki circle ko humme arbo tukdo me kata tha or unse jo rectangle bana toh rectangle ke length me wo divide ho gaya aada circumferemce ka hissa upar h or aadha neche
Thanks sir for knowledge
Very good attitude
Area of circle=22/7 r^
Nice bhai aise hi experiment karte rahiye
Thank you so much sir
Most welcome

Sir mera comment delete kar diye kya
Super explanation
यदि परिमाप २२ है और व्यास ७ है तो क्षेत्रफल क्या होगा
From where we calculated the value of pai.you say it is a constant i mean from where or how we drive or calculated the value of this content number .Is it a theoretical figure or merely speculation figure.
धन्यवाद.सर.
Kai salo baad aaj fir math smjne ki koshish ki..per kambakht neend ab bhi utni hi jldi aa jati hai..
Good explanation
