    I have such a bad feeling - has anybody found a mark scheme yet?

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

    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?

    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)

    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
