    I don't think the radius was required for the area as it was just the first 2 circles involved
    Ah right that'll explain it. I got 4 + root 7 for the radius : (

    Also it appears I got the wrong radius but the right area for Q4?!
    possible the radius of C3 has nothing to do with the area.

    I think the idea was that if x^2 + 1 is a factor then subbing in x^2=-1 should give you 0, which only works if n is even

    There's probably something I didn't think about that makes that wrong though
    I think all the powers where raised by even numbers within the brackets. Can't remember. But i screwed that one up by thinking x^2=1. So frustrating

    I got 10 combinations but 107 and 117 for c? I couldn't explain why they were the values though.

    I got 10 combinations but didn't use any logic just that b had to be applied 3 times and a twice or something then I justsat for ages and worked out the combinations. got 107 for c I think

    4root3 - 11pi/6 I think. Certainly 4root3 minus something pi.
