I have created 8 fiendishly difficult questions which use the equation of circle. As it is aimed towards GCSE students the centre is always (0,0) but they link in other topics such as trig, solving non-linear simultaneous equations, equation of tangents etc…
The PowerPoint is the editable version, but there is a PDF version which is easier to print. The answers are also attached.

Update: Q3 the answer should be 14 1/12 as shown in my working out, on the next line I put 14 1/2 by mistake. The answer should be 238 1/120
Q5: I forgot to subtract the semi circle, the radius of the circle is 10, so you need to subtract 50pi off the answer given

Something went wrong, please try again later.
Thank you.
Excellent Resource.
I think there is also a typo in q3 which give the triangle area as 1/2 * 33 4/5 * 14 1/12 =238 instead of 245 1/20. The typo was 14 1/2 and it should have been 14 1/12.
Thank you.
