The formula for finding the circumference of a circle is 2πr or πd
So, there are 2 ways to find it.

1) Using the diameter, you would do π x 14.
This will give you 43.9822971503
(round the number to however many dp it says to do :) )

2) Using the radius (half of the diameter), you could do 2π x 7
which will also get you 43.9822971503

You have to use a calculator for both of the exact values using sin^-1 or Cos^-1 you can then times those together, with the final part the answer is sin 240 as sin(A-B) = sinAcosB-CosASinB
