Talk:A-level Mathematics/OCR/C2/Circles and Angles

I have changed 15° on the radians example to 20° as this makes the answer 1/9π rad

I also think that on the arc length example the answer should become 5.550147021cm = 5.55cm as 33.3...cm is quite large for a circle with only a 6cm radius and 53° angle. I will change this to the answer that I think is correct unless someone else disagrees.
