    I've moved this to the maths forum, where hopefully you'll get some help.

    However, it's better that you just post the question rather than ask for PMs.

    Yes, it's always better to post questions here. You are more likely to get a response, and mistakes are more likely to be spotted

    I'm finding it difficult to even start this, I tried converting the bearings to decimal degrees and going from there but I'm not sure on how to move forward from that!

    Can you work out the co-ordinates of the circle's centre and the circle's radius?

    I'm not understanding what the type of equation given is. If it's already in the correct form, would you not square root the 96.25 to get the radius?

    Okay fair enough. The numbers are disgusting but its doable. The key thing here is that the arc length is given by r\theta where r is the radius, and the \theta is the angle of the arc.

    That diagram is extremely messy so here's the simple version:




    Have a go at finding finding this angle, it really isn't anything difficult, just time consuming and the numbers aren't very nice.

    No... the equation of the circle is (x-a)^2+(y-b)^2=r^2 where you read off the coordinates of the centre and radius.
