    Question 8b

    don't know how to show that at all
    tbh i'd just say 2\pi r = 2\times \pi \times 12

    then minus my answer from part a by the answer i just got, to get an answer for part b i mean why so complicated? :/

    Draw a triangle OPQ, you know the lengths of two of the sides since they are the radii, then you can find the length PQ whihc can then add to (a) to get the answer.
