Guys wasn't part a of Q9 = 1/3pi(x^2)????

because the sector area is 1/2r^2(theta)
which is 1/2(x^2)(2/3pi)

= 2/6pi(x^2)
= 1/3pi(x^2)
??
YUSSSS i was going to mention that... he didnt multiply by 1/2 i guess

If you put an answer that isn't in the range eg -14.5 do you lose a mark?

Probably zero
might only get 90 ums then. Actually just checked with my teacher and he said 2 marks for showing manipulation of logs so could get 95.

Wish I could go back and see the question, I can remember being 100% sure that I had gotten the correct answer.

nope, he's right. x value was 10, y was 13. Those numbers don't compute in what you gave.

I agree with every single one of the OP's answers.
Difference between U9 & U10 is incorrect.
He probably used ar^n

It was the difference between ar^9 and ar^10 wasn't it?
a = 64
r = 3/4

Can someone confirm?
