Maybe TSA of a cone? http://www.mathsteacher.com.au/year10/ch14_measurement/18_cone/20cone.htm

For TSA of a sphere I remember it as differentiating the volume formula with respect to r.

The formulas of a segment or chord could be useful, but aren't necessary since you can work out what you need with trig and basic circle knowledge.

Hey I wouldn't know for specialist mathematics; however, I can make a comment on methods through my encounters. From general observation is has become apparent that the following are required:
-Knowledge of similar triangles
-Geometry from Year 9 (this depends on what you're school taught you but generally if you did 'advanced math' all the geometry from then would be applicable I would say)
-I have come across questions which require your knowledge of the properties of a circle.


I don't know if all these are set in stone; however, mathematics is a bit different and to my knowledge VCAA could examine us on anything that we have learnt in our past years in maths. I wouldn't be completely sure but this is all I know so perhaps it is worth brushing up on middle-school geometry.
