Never thought I'd be having to learn 5th grade math all over again at 28 years old but here I am. Thanks for the videos!
this is 7th grade math idk what ur talking about
@@youssefalwehaib527 umm
Say it like "For me, i learned this when i was 7th grade"
Not say "uhh this 7th grade math"
Because not everyone learns anything at the same grade ya know
i am just now learning it in 7th grade and i hate it but this video helps
wow 🤣
@@youssefalwehaib527 it depends on where one lives i guess
Bro turned an entire lesson into 6 minute video
Thank you, I need this for my final math exam 💀
ikr it saves time so much-
Bfrr
me 2
Yup
Me toooo😭😭my grade will be a C if I don’t get a B 😭
Blud teaches more than a teacher for a 6 minute vid to an hour good job!
Sir tysm I’m abt to do testing so I’m reviewing some math questions. This really helped me I never thought the area of a circle be so easy!
Happy to help. Good luck with the test!
Yeah it was really easy
Same
in school i learnt that if a number is able to divided by 7 then it could use 22/7 is that correct or no
@@Hydrationator2 Yes, that is correct. If a number can be divided by 7 without any remainder, then it means the number is divisible by 7. In such cases, you could represent the division as a fraction using to get an approximate value for simplicity or ease of calculation.
Boiiiiss Because Of This I Almost Had 100 In My Math 🤣 I Had 97(Grade) Thx For This Guy's Vid's,
Thank you soooo much mr. J
Hey there !!
Thanks so much, Sir! My final exams are in a week! this helped me so much! please continue making videos :3
Hey I got an end of term test form 2 and I really don't understand the math so I'm here willing to pass mathematics😂😂
Thank you so much!! I have a test coming next week and like most people watching this are struggling like me. But this video really helped me out!
life saver, always can trust and watch your videos to help me understand math. 6 minutes and I totally understand it now. better at explaining than my teacher. thanks so much for this ❤
САМИ, мой учитель тоже так делает-
i believe you made a smaller error in finding the area of the first problem which consist of the radium being 3 inches, because if i followed the formula correctly 3 squared equal 9 , then multiplied by 3.14 gives you 28.26 not 28.27.
I noticed the same thing I was replaying the video a bunch of times scratching my head trying to figure out how he got 28.27 I got 28.26 and even typed it in the calculator and got the same answer..
@@Malik-mx8st I had the same issue, but if you use the pie symbol on your calculator instead of using 3.14 you'll see how we rounded to get 28.27. You may have to switch from a basic calculator mode to scientific if you're using the one on your computer.
28.2743 = 3x3x3.14159
Im getting no 28. Anything out of this and im using a calculator on an iphone. Simplified this problem is…3.14 aka pie, times 3, 3 being the radius multiplied with pie gives you 9.42477796, squaring that to itself makes it 88.8264396, all of the multiples in this number are multiples of pie.
But i am not getting a 28 from anywhere…
This helped me a lot to study with my test! Ty for your videos sir!
Thank you! I’m testing as well and this helped me as well
Thank you so much, I love all of your videos. They have been so instrumental. Thank you again!!

Isn’t number 2.) 12.56 tho?
4:58
he said 'hundredths', then said and wrote 'cm', but the unit of that circle was in ft.
this helped, thank you
Yes, helps students if the solutions are correct!
True
I learnt this at school but didnt quite understand it, this helped alot!
All the other videos were confusing me
I look at this and was like "wow I didn't know it was this easy"

Really helpful. Thanks!!!
Thank. U so much for this, my 7th grade math teacher DOES NOT know that we JUST came out of 6th and we need to deep defitions about certain things especially the kids in my class so thank u so much for teaching this to me
FOR REAL IM IN 7TH TOO! bro like when i got into 7th grade my teachers didnt even tell me what Pi is or anything like diamter or circumference
Hi sir, thanks so much! You always help me whenever I have difficulty problems with my work! You just earned a new subscriber 😊❤
this is so help full I have adhd and this really helped because I was able to concentrate well
When do you round them? Is it only when you have decimals?
Saving my math grades since 2nd grade thanks!
Rn I’m on. A zoom and I was so confused about the thing we had been learning for months cuz my notes were ruined! I am doing an assignment and this is SO helpful
Thx so much
90% understand😭😭😭den watch it over and over I finally got it ... Ty🙃
Wow this was so easy. Thanks a ton!
Thank you Mr. J. This is a big help. One thing I have a question about is, why did you round to the hundreths place ? Is this a rule when finding the area of a circle?
No it’s just that pi has never ending digits so he just rounds it to the hundredths place
I think you were a little late🔥
Thank you so much this helps me with my grades. I look at your videos everyday and it helps thank you so much!😊
That is awesome to hear! So glad the videos help. Thanks so much for watching.

Mr. J I'm trying to figure out the area for a triangle that has semi-circle on all three sides. The triangle has 4 1/2 in. the semi-circles each are 5 in. Can you help me. Thank you for your time Nancy
Tysm mr J i really learnes a lot math from you! 😁
Best teacher and thank you 🙏🙏🙏👍👍
for number 3 was it supposed to be ft squared, as 50.27ft sqaured, instead you put cm squared
Bro you help me so much!!
Tysm!! I have a selective test and I need to know all about pi, thanks!
Thank you sir for your explaination
i got very different answers think that that is wrong or my calculator is messed up?????!
i got some too-
You probably squared the number you got AFTER multiplying the radius by pi. you need to square the radius before multiplying it by pi.
Thanks that is a big help in my test or assignment
One small comment how do you get cm squared when the measurement is in feet in problem #3?
Tysm sir my homework was due today and it really helped😊
Hi sir... i love your videos i easilly start to understand my work that i thought was impossible. I am preparing for my exams and this video helped me alot!!!
My point is .... thank you 😊

This helped a lot i have a quiz tm and it made mire more sense 😊
this was really helpful thank u so much I hope u don't mind if I share this vid.
Why for number 3 did you put units as cm instead of ft?
Thanks J you might be the reason I can ace my selective test 🎉🎉❤❤
Thanks bro I needed this I have a test tomorrow
thank you.. this helps me so much :)
Thank you so much my homework was due in 5 mins and this saved me
*_uuuuuuggHHHHH_*
these videos make me feel so dense- i just wanna do quarantine in peace without work --
pansi the waffle 2 same here bub
Thank you for the video, actually for all of your videos. I have a question though. Why is the answer to the third circle in cm, not feet when the radius is 4ft? Please clear up this confusion for me.
Because they labeled it as cm not in so then it would be for cm instead of in if that makes any sense
Because he gave the wrong answer!
thank you this really helped 😁
this the best teacher my teacher takes multiple days to teach his 6 minute lesson
Your channel is so helpful
