    for area of segment i did 1/2 x r squared x sin35-triangle and the found area of sector,then i misused them from each other,is that right??
    Nice If you got 119 for area of segment, then that's correct.

    Did anyone get something like 20x^2+20x+5 = 20x^2+21x-5 In the end question.
    I was stuck on this bit for ages and then I realized -5 from -5 is 10. Lol.

    If you calculated upper bound as 3.61... and lower bound as 3.59.. then you would probably get 3/4 marks. 3.6 is the final answer and had to give reasons.

    was workingout correct mate?
    I think so. for area of sector i did angle/360 X r^2pie
    Then I use the area of triangle rule to find the area. Finally subtract area of sector from area of triangle

    yes if your quadratic equation was simplified

    yeah, you should get all the working marks because usually it's only one mark for the correct answer and the rest of the marks for the working.. so thats like 4 marks
