It was hard for the most of the people in my school, i manage to do them after second round, but i missed out the "show" the real roots part in the last question before finding a and b, Do you remember your answer for the area in the last question..? and the circular measure part?

Yeah......the answer was 11/12 pie ;)
Am afraid to tell you that but the answer would be 2.88 without pie.
Though your method (pie x integration of [y12 - y22]) was correct.
Initially I did it the same way you did but got a negative value as answer. So I decided to do it step by step and I finally obtained the correct answer.(according to me and my friends)
