For the formula of the are for the sector I have: 1/2.r.r.θ
Thanks for these videos, I have my C2 maths exam tomorrow (well it's 2am so basically today) and I'm so nervous I've been solving past papers for hours. The worst for me is solving log!
not sure what the difference is between the two equations for the area of the sector of the circle for radians and the area of the sector of the circle for degrees. When i used them both they both came out with the same answer. (great videos by the way, really helping me a lot!)
i hope i get a question like this on the exam for 11 marks.
very useful videos.

Something tells me you've had issues with a student who has calculator-related OCD and can't wait to get his calculator back into degrees-mode, lol.

@Nenjaw Common mistake - happens all the time.

Thats one of a few ways of doing it.
I went basic pythag for sqrt 31 then (bh/2) for triangle and took 1/2r^2theta from that
