Sir ap bahut mast vedio banatai ho or samajha tai ho plz iski or vedio banado l request sir plz ...... Plz sir e.g cubiod , 'cube , cylinder, total surface area a cylinder etc plz sir .....
Cube, cuboid, cylinder..ye to esy h. i)ᴄᴜʙᴇ..square se bnta h, cube me 6faces hote h yani 6sqrs 1sqr ka area agr a² to 6faces ka 6a².. => TSA=6a² Same, LSA=4a²..bcs 4faces hogye Yani 4sqrs ii)ᴄᴜʙᴏɪᴅ.. Ye 6rectangles se bnta h.. Top & bottom dono same dimensions ke h l & b.. To area(top & bottom)=lb+lb=2lb Ab 4walls.. To ek side ke opp walls ka hoga bh+bh=2bh And othr side ke opp walls ka lh+lh=2lh.. So, tsa=2(lb+bh+hl) iii)ᴄyʟɪɴᴅᴇʀ.. Ye circle se bnta h.. Circle ke upr circle rkh ke jse sikke ke upr sikka.. CSA=2πrh.. 1circle ka crcmfrnc=2πr..ab yhi circumfrnc pure h height tk ja rha h, that's y..2πr×h=2πrh Baki total ke liye top & base ke circles ke area ko add kr do.. To TSA=2πrh+2πr²

@@BabitaKumari-ui7ez R aur L different hai. R cone ke base ka radius hai aur l cone ka slant height hai. Btw wo same hote to bhi cancel nahi hote r² ya phir l² hota
Excellent and very useful video, Sir. Thanks a lot again sir for teaching us Mathematics with your best teaching skills are care. A lot of respect and love to you, Sir ❤️❤️ Take care of your health 🙏🙏☺️☺️ Sir, please upload this videos on your 'Edunext maths 9' Channel.
@@BabitaKumari-ui7ez 'r' and 'l' are not same. 'r' is the radius of the Base of the Cone and 'l' is the slant height of the Cone. Therefore l² = r² + h²
Sir ap cone ki slant height ko length consider krte ho lekin maine padh ha length horizontal measurement hota hai so cone ki length slant height kaise huvi plz reply ma boht confusion ma hu plz reply
This video is awesome, superb and very knowledgeable for ""MATHS LOVERS"".

Cylinder is also kinda ez

Better than Best ☺️🔥👍👍
Thank you sir very much 🙏 U explained every step clearly and in detail
Being a teacher, I felt the video was super. This will definitely help my students. Thanks.
Thank you very much sir ....
I was struggling for that ....
It's superb....this type of education is required in our schools....perfect
Wow,very nice sir🙏🙏 bilkul sahi , formula to nikalna batana hi chahiye ,sab direct formula rata rahe hai ,aap perfect teacher hai 👌👌👌👌👌
Excellent teaching. Very conceptual and lucid.. majaa aagaya sir ji !!❤❤
Wonderful explanation sir never heard such a clear explanation from anyone.Thanks alot guruji ❤️❤️
♥️♥️♥️ amazing pls 🙏 make formulas for frustum of a cone
Great practical guide
Thanks a lot, this is the easiest solution to this problem.
Brilliant sir explanation 👏
Tysm..i ws literally confused in this topic..u made it very clear..thanks once again

Sir ur explanation is good
Very well made!!
Helped a lot... Loved it...
Adbhut❤️
Wao! Mind blowing
Sir I am big fan
Amezing 👍
I do not know Hindi. But I clear understand this video. Because diagram great hlepful .
Perfect explanation sir super super super 👏❤️❤️❤️❤️😁
Thanks a lot sir i understand the concept very clearly 😃😇
Sir why do we need to take PI in circle case.
Best educator
Legendary 🔥
Helpful☺️
Nice
Very well explained
But area of Sector (1/2 l. r) bhi hota hai us se or easy ho jaiga
Which software do you used to make this video sir?
which software is used to make such videos/animations?
You are great teacher.
Thank you very much for your huge support.

Teachers school me ratuu Vidya hi dette hai kitni Sharma ki batt hai excellent work
What if the angle is given to us then we can use the angle to know how many times of this circle is this sector right?
Very beautiful ❤
awesome way to represent........May I know which software you use to represent these lessons ?
Power point
Very good explanation 🙂
Very nicely explained
Great video 👌🏻
sir please make a video on why the cone have 1 by 3 in its volume formula
Thank you sir please make this type of video
Supper sir ur explanation
thank you sir
Amazing video 😌

Superb Sir
Hi jaise baccho ka sahara ho bhagwan aapko sadaiv khush rakhe
Beautiful demonstration, detailed and progressive. Thanks! 👌
tq sir simple nice explntn
Wonderful!
Thank you sir.
Bhut op💥
Sir similarly sphere ka volume & surface are bhi explain krein pls..
appreciate you from Pakistan
Mahan karya kr rhe hain aap
Great 👌
Very helpful
Very helpfull video
😮
Nice!! 👍
CSA of cone =Area of sector
= 1/2 length of arc× radius
= 1\2×2πr ×l
= πrl
Super explanation
Thank you so much sir
Amazing..❤️
Berry nice editing
Excellent
Thanks sir
Sir please aap hummari cube ,cuboid kai b video lecture aaisahii deknayia........... Because aaisa aachay sai clear hota hai plzzzzzzzzzzzzzzzz sir
