# Edexcel Maths - 4th November 2015 watch

1. Now embargo is over - let's discuss!

I have such a bad feeling - has anybody found a mark scheme yet?
2. I know a few answers but haven't found a mark scheme

what did you guys get for cone and hemisphere question?

I got 4/3 x 9 cubed x pi divided by 2 + 270pi = 756 pi

same and did u get 110/8 for the trapezium

I cant remember my answer for that one

I cant really remember a lot abut the question but I had the square root of 81

I got 324pi

you did surface area
9. Wait a second, now I realise where I went wrong I did 4/3 x pi x 9 to the power of 2 to give the the volume of the sphere, then I divided by 2 to give me volume of the hemisphere. I should have done 4/3 x pi x 9 to the power of 3, then divided by 2 to get the volume of the hemisphere which would equal 486pi then add the volume of the cone 270pi to get a total volume of 756pi cm cubed. I am so angry with myself would I get any marks?

I think you may get one or two for working
11. Can someone tell me what that cone question was? Like the actual question? I didn't sit this paper, but I'd like to give it a go (and I could act as a markscheme for you guys)
12. Ok. I've done the question about the cone/hemisphere. It was actually really easy. Just required basic algebra skills. Hang on I'll post a picture

Yessss same
14. (Original post by ryanbraithwaite)
Would u get a mark if you write in decimal
15. Someone give me the trapezium question ill do that one too. There's the cone solution
Sorry for blurriness
