Trial and improvement answer was different for different methods. Working out 3.75 would give you the answer 3.8. But doing it this way:

3.7 = 34 - 32.153 = 1.847 (the amount 3.7 is lower than x)
3.8 = 35.872 - 34 = 1.872 (the amount 3.8 is above x)

Would give you answer 3.7. I don't know what they will accept as the correct answer.

Was question 10 the perimeter of the shaded region in the circle??

You mean the shades region of the 2 sectors? That was more like question 21

Believe this was the answer to the last question.

I managed to get the workings to 40.005 degrees. But I stupidly put this as the final answer!! Do you think this will get me 1/2 or more marks?!

Did you're teachers say this?
3.7^3 - 5(3.7) = 32.153
34 - 32.153 = 1.847
So 3.7 is 1.847 away.

3.8^3 - 5(3.8) = 35.872
35.872 - 34 = 1.872
So 3.8 is 1.872 away.

This shows 3.8 being 0.025 further away than 3.7. 3.7 is closer. This is why i put 3.7, but idk, people are getting rather rowdy at me for putting this idea forward xD

Thats exactly what i done and my teacher agreed, she done the paper with us after the exam its 3.7
The difference is soooo little but it was 3.7 trust me
