Equation of a circle - GCSE - Difficult!

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.

Leave a review and let me know what you think

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
