FP3 2014 gives students the chance to prove the surface area of a sphere is 4 pi r squared. Interestingly four time the area of a cross section through the centre and the derivative of the volume. Pupils with strong maths general knowledge from GCSE would know what is coming. TOP TIP do as much maths challenge and extension work as possible, the general knowledge thus gained can only help. This FP3 2014 paper and many others are at my Exam Bucket: http://jped.co.uk/ExamBucket/exambucket.php.
