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)
??
I got this!

but then a would be 1/3b - something- a lot more awkward number. I can't even remember now.

Yes I think it was -2.19. I had log7/log2 - 5, which gives -2.19. For a I think it was 9b+5 divided by something, I think 2?

it was definitely +5 as it was y-13= -3/5(x-10)
so
5y-13=-3x+10
This is wrong, you haven't multiplied the 13 by 5 when you took it across

you forgot to multiply the -13 by 5 to give -65
