You don't know how many people you're saving from the fear or math, which I've always had haha. These kinds of vids help me alot, couldn't thank ya enough.
I cannot truly thank you enough. This video has got to be one of the most praagmatic yet verry digestable math tutorials Ive ever seen, I love how in depth you go into explaining the formula and why their shown that way. Under-standing how it works just makes my knowledge about this topic that much more flexible and logical. Sorry for glazing but this video deserves it, to anyone else reading the comments while watching the video, trust that you and your quiz grade are in good hands❤❤
I first set up the equation (using proportions), plugged in the numbers, then solved for arc length! Let me know if there’s a specific part that you don’t get
@Heather Gillette Ohhh nevermind I get it. The radius is 6 so the diamater must be 12, therefore 0.222222 is multiplied by 12 cuz its the diameter and you get 8.37, rounded to 8.4. Ty
How do I solve for a sector if I have the angle and the arc data, but not the radius? … I watched many videos and this one was the easiest to understand, thank you.
Great question! I’m thinking you can first use the angle and arc length to find the radius (like in the first half of the video). Now, that you have the radius, you can find the sector area (using the formula in the second half of the video)
Hello what engineering did you study or which US uni. Im looking to find good us engineering unis to transfer to from a canadian math undergrad (uoft). Thanks
Hello! I studied biomedical engineering and was choosing between ucla, usc, and carnegie mellon. I ultimately chose usc (for reasons other than their engineering program). Other great schools are MIT, caltech, georgia tech, university of Michigan, university of illinois. Let me know if you have any other questions!
Thats by substituting the values of π and r and then simplifing. So hasn't shown that working part. (80/360) × 2 ×3.14×6 Hope i could help you out of ur confusion 😊
another formula is: x°/360°*2πr all u do is plug in the values, in this case it will be 280°/360°*2πr you solve that and you get 8.377 which rounded off is 8.4
i was so confused as well she didnt explain that you change the pi symbol into 3.14 then you plug it into the calculator and round. honestly pissed me off so much because i kept plugging in the pi symbol and kept getting syntax error. i figured out that you can still use the pi symbol if you want if you do it like this: 80/360(2 x π x 6) and you get the same answer. dont add spaces i did it to show it better and i used the same numbers from number 1 at 3:19. hope this helps buddy

Thanks for watching!

Why is the last answer in square inches? I believe I missed something obvious. I appreciate your help!
I cannot explain how helpful this was, I have a unit test in trigonometry and this saved me. Keep up the good work

Thank you! I haven’t posted a video in a while but it really made my day reading your comment 💛 I’m so glad this video helped
you explained it better than my teacher! thank you :D
btw if you want to find the meters at the end use: (80/360)x(3.14 x (6^2))
Thank you 🥰 I’m so glad this video helped!
Do you divide the 80/360 and then find the result of 2π6 and the multiply it??
Thanks I finally understand how to do this after like an hour or two of just looking for videos!
ok here comes the best math tutor everrrr
Wow, this really helps me to help my son with circles. Great teaching.
I wasn’t been able to solve some problem,thanks you a lot,keep up the good work
Thank you so much . Been struggling for a while 😭😭
Thank you so much, you are a great teacher
You're the best, Thanks for thorough explanation.
U got a sub
Very well explained.👏
Please can you do a video on the other ones like segment, perimeter of a circle and the rest
Thanks for the video
Also can you do more proof videos, like for linear algebra or real analysis. Theres barely any on youtube
Sorry my channel is focused on high school and middle school math! Have you checked out TheTrevTutor on TH-cam? Also office hours helped a lot
Omg thank you! I was so lost
Omg ur the best
I was so confused
Lol western maths gotta be more easier than Asian
Exactly!
literally retesting on this tmr
I have a question, How you get 8.4 meters in the first problem?
I first set up the equation (using proportions), plugged in the numbers, then solved for arc length! Let me know if there’s a specific part that you don’t get
@@yourmathtutorvids How did you solve L=80/360(2π6)
@Heather Gillette Why do you multiply 0.222222 by 12?
@Heather Gillette Ohhh nevermind I get it. The radius is 6 so the diamater must be 12, therefore 0.222222 is multiplied by 12 cuz its the diameter and you get 8.37, rounded to 8.4. Ty
@@yourmathtutorvids miss no offense but you're not that good at going into detail w how to actually solve it.
great video!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thank you!!!
super helpful!!
THANK YOU SO MUCH OMGG
THANK UUUU 😭😭😭😭😭
Thanks a lot

Literally saving me rn 😭
Sorry how did you get 8.4 I'm confused
Thats by substituting the values of π and r and then simplifing. So hasn't shown that working part.
(80/360) × 2 ×3.14×6
Hope i could help you out of ur confusion 😊
Just calculate with a scientific calculator?
thank u
Ok, I’m
Confused. We first divided 80/360 then what’s next?
Then multiply by the circumference if you're solving for arc length.
Or then multiply by the area of the circle if you're solving for sector area.
3:14 wait you didnt say where that answer even came from😟
another formula is: x°/360°*2πr
all u do is plug in the values, in this case it will be 280°/360°*2πr
you solve that and you get 8.377 which rounded off is 8.4
Take out yo scientific calculator boy
How did you get 8.4 in 3:19
i was so confused as well she didnt explain that you change the pi symbol into 3.14 then you plug it into the calculator and round. honestly pissed me off so much because i kept plugging in the pi symbol and kept getting syntax error. i figured out that you can still use the pi symbol if you want if you do it like this: 80/360(2 x π x 6) and you get the same answer. dont add spaces i did it to show it better and i used the same numbers from number 1 at 3:19. hope this helps buddy
it supposed to be multiplied with 12 pi because (2 * 6 pi), yeah he missed calculating that part
problem 1 s answer is 8.37
ESCAPE THE MATRIX GEEKS ❤️🔥
oh yeah lemme just drop out of middle school and escape the matrix smh
I thought the formula was Fraction of Circumference ×2pir for arc length
my only question is how are your "r's" shaped bro
I don't understand because it's so hard to find degree😢
You didn't explain how you got 8, 4
They just put the equation with the substituted terms into a calculator.
(2)(🥧)(6) = 37.68
80/360 = 0.22
37.68(0.22) = 8.4m
More. Harder question
she did a terrible job at explaining the first one
Hello! Is there something that would have make it more easy to understand? Thanks!
