This video is a tutorial on Circles. Please make yourself a revision card while watching this and attempt my examples. Straight away then move to my video on Circles 2 - Exam Questions 8. This video is for students attempting the Higher paper AQA Unit 3 Maths GCSE, who have previously sat the foundation paper. Explanations are aimed at being as simple as possible and so students who previously did the Foundation paper can access. They would also be useful for students who have always sat the higher paper. www.hegartymaths.com www.hegartymaths.com/
For me fractions are always best. Much more useful but decimal is acceptable. Mr H
These videos were just tailored for students not sitting the higher. They cover the majority of the course. Vectors are in my gcse higher revision playlist and well as equations of proportion. Only topics not with videos are transformations, graph transformations and drawing quadratics. glad the videos help!
Wouldn't the perimeter ( 11:30 ) be P=6Pi + 12 ?
No

@@ichangedmynamelol2795 🤣🤣
yes.
@@kadir7940 Thank you, it's been bugging me all these years. I have some closure, and can move on, now
12:00 Most useful bit
It might be for you
Wouldn't the perimeter ( 11:30 ) be P=6Pi + 12 to make 30.8cm?
ya it is 30.84
Now im sooooooo confused??????
Happy Me No
The answer is 18 cm. Is that right ?
0.5 X 2 X pie X 6 = 6π. This is half the arc. Then add 12cm which is the diameter which = 18 cm for the perimeter or 18π...
Yes he has forgotten multiplying by half. Should be 30.8CM
Sorry, I should mention that my calculator is CASIO fx-83GT PLUS.
thank u so much. ur explanation is amazing
hey the perimeter is 6 pi not 12 pi so check on that
Thank you so much Sir for point this video.
bless upon you.
This tutorial is very useful plus its help me a lot by understanding the method of doing it. I wish you be my teacher.
Time Thomas could be*
10:50 mistake lad!
ABSOLUTELY! Maths is maths and there is so much cross over between AQA and EDEXCEl. But just make sure you have a copy of your syllabus to check now and again. Stuff like circles, trapezia, quadratic formula and all standard maths will be in both boards
Sir, you say this playlist is for students who were "previously doing foundation and trying higher" so does that mean the playlist is for the basic Unit 3 knowledge or absolutely EVERYTHING in Unit 3? I am an originally Higher paper sitting student and am sitting Unit 3 early, on March the 6th so I need to know.......
Your videos are great btw and really clearing things up for me
THANKS
Thank you so much for these videos! I'm so glad I found your channel a few days ago. My exam is on Wednesday (AQA Unit 3 Higher) and I'm really hoping/trying for that A* and these extra bits of revision/clarification of some parts that I do not fully understand might just do it for me! Once again, cheers
Its under the Abs button with two squares on top of each other. type 60 then that button then 360 - that should do it. If still stuck just use brackets and type (60 divide sign 360 ) x the pi r squared for example.
Best of luck!
thanks very much.keep on
hello Mr Hegarty, where did the 2 come from on 18:28 question 3 to get the answer 5/3 pi?
Thanks Sir
isnt the circumfrance of a circle Pi x diameter? thats what i got taught at school and you get a different answer when doing this compared to the 2 x r x pi?
LouisClarkeClare well double the radius is the diameter ☺️ you can do 2PiR or PiD
Thanks very much! Your videos are very helpful, thank you.
thanks I really appreciate your hard work. The difference between your work and other people is that you do go over the concept before treating the exam questions. Although my children are doing edexcel higher but I will ask them to follow the way you are doing it in the AQA Maths as Maths is the same anywhere you go as you rightly said. Thanks again for your hard work
Impressive
circumference= 2*3.14*r = 2*3.14*6 = 37.7.........half the circle /2 = 18.85 then add 12 (6+6) = 30.85.........please explain
I got the same thing
This is now Foundation.
Muhammad Amer Nice u copied a comment
Oh, ok :) great video, and thank you for helping me with my revision!
thank you
Once again thanks for the great videos!
Thank sir
Correct than you for this - I have made a note adjustment! Thank you. Mr Hegarty
When giving your answers in Pi, do you have to leave them as fractions? eg 5/3pi cm or can you witre them like 1.6pi cm?
Check out mine to put line a pie would be section
However mine is 3 sector math desifering
Computer codes from each month
Do we need to know about stretches of graphs and other graph stuff for the exam on friday?
I wish you could be my teacher
Thanks for your videos. Is it possible for students doing Edxcel Maths (Higher) use your videos.
Hi,
Thank you for your help. I am an adult learner preparing for the higher tier paper ths coming Tuesday and Friday, as is everyone esle I expect.
I am not the brightest maths student and you talk about doing 60/360 on your calculator. Could you please tell me how I do that. I have tried reading the instruction manual and I have tried to google the answer but no one gives the answer as plain as you do.
BIG thanks for all your help.
cherry pie delicious
C = (P) d
(circum... = pie ×(d)iameter
apple pie are to
A =(P) r 2
area= pie × (r)adius squared
Really? Is this Higher math? I did this in 4th grade!
How did 3 x 3 became 28.3cm(squared)
Radus?
for finding the perimeter it is supposes to be 30.84 ..... I thiink he miss calculated
I subscribed thank you very much
In 11:29 u have made a mistake. The perimeter is 30.849555592
1dp
This is now foundation
ye but exam questions will make it harder because of the way they are set out
and half of the higher paper has foundation work
Nice to meet you
We''ve learnt that it's Pi x diameter too. The diameter is double the radius though, so 2 x r x Pi would also work :)
I love you :)

Hassan Abdelrahim ok...
A bit sketchy
why you sound like DanTDM
just jam he doesnt
