Area would be 4.52 A= pi x radius squared
Circumference would be 7.54 C= 2 pi radius. Hope that makes sense.

If you are trying to make B the subject, you have to divide both sides by 'h' because we need to get rid if 'h' to get 'b' on it's own, and you do the opposite of times - which is to divide. Once you divide both sides by h, you should end up with this:
A/h=b
The graph represents f(x)=-2x-1
Number 28 is 36 because if you look at the ratio on the left of it you see that it is 81:81, which would mean that 36:36.
