This is great and easy to understand the most important thing of all time is to crasp the maths formulae and know how to apply it thanks may God impact your brain with more knowledge great
Excellent question! Let me know if you figure it out! I had a try, but it needs more thought. I made the two formulas equal one another and attempted to get the angle (theta) on its own, but it is a work in progress for me...
Peter Blake I ended up just assuming the radius (1) and setting the area and perimeter equations equal to each other so theta was the only variable left and solved for it
@@julianagraceffo3291 Very well done! I tried that approach and did something wrong. I was intending to have a second attempt, but as Robert Frost described "way led on to way" and I was distracted by something else... Glad you sorted it.
Hi Dan, If you have the area (and the radius, I hope) you can work backwards to find the missing angle. To find the angle, take the area and divide by pi, divide by r squared and then multiply by 360. Then you can use the radius and the angle you found to get the perimeter as described in my video. Hope this helps, buddy!
Hi Lina, Good question. If you don't have the angle, then the question should give you all the other values in the formula. I suggest writing the formula on one line and all the values you are given underneath. You then can work backwards to find the angle. To get the angle on its own, you would be taking the perimeter value, subtracting a radius, subtracting another radius (press = at this point), multiply by 360, divide by 2, divide by pi and then divide by the radius. You should then be left with the missing angle. It sounds very complicated, but all we are really doing is working backwards by moving items away from the angle until the angle is on its own. When we move items to the other side of the = we do the opposite operation, don't we? If you are still a little confused, please leave another reply! All the best.
Thank you thank you thank you!!! My teacher spread this out into an hour-long lecture, you made it short and sweet, I can't thank you enough.
Good to hear. So glad it helped!
You have no idea how much this helped me, thank you.
I'm very pleased. Thanks for leaving a comment. I appreciate the feedback.
This has helped me with my online maths class
I am very glad.
me too brother
This is an absolute life saver whilst remote working! Thank you
Great to hear! All the best... Thanks for your comment.
Love this, helped a lot :D
Also, gotta love the commitment of replying to all comments, 7 years after the video was made
Good job!

THANK YOU SO MUCH, SIR PETER! You are a huge blessing to this tutor who is completely lost in her student's math lessons
You are very welcome, Abigail. Glad to help... All the best with your tutoring!
DIOOOOS.

Happy to hear that! Glad you enjoyed my Australian accent!
Thank you this helped so so much. Could you do a video on quadratic equations?
Thank you
Already uploaded. There are 10 key examples in this video. Hope it helps! ruclips.net/video/sN5cQVASVMk/видео.html
So helpful 🙌👏
I am so pleased! Thanks for your kind comment!
thank you so much. i finally understand
Glad it helped!
I am from India.love the way you explained it.Thanks for your effort it helped me alot.
So nice of you.
how would you find the angle of a sector whose perimeter and area are the same?

Very help full vedio
Thank you! I'm glad it helped you...
Thank you I would fail my class but this video help me
Awesome. Glad it helped...
really good video understood it well
love how he still replies to comments even if this video is 6 years old
Glad to help. Anytime...
Thank you.
You're welcome!
Thank you so much for the video without this I wouldn't had pass my math! ❤️👁️💧👄💧👁️👍
So glad! Well done on the pass!
Cheers, thanks for the help!
Glad it helped!
It helped me a lot🙂
I'm so glad!
it helped me on my online school thank you so much
I am so glad, Alessandro! Thanks for your comment.
Very nice
Thanks
