1. ## Surface area/volume

I've got a test next week, and I can't remember the equation for the surface area and volume of:
a) a sphere
b) a pyramid/cone

the volume of a sphere is V=[4pi(r^3)]/3
the volume of a righ cone is V=[pi(r^2)h]/3
the volume of a right pyarimid is V=[(area of base)h]/3 which is the same as [pi(r^2)h]/3
were r is radius and h is hight

But isn't the ultimate goal of a teacher to teach a student to be able to learn on their own? The guide to self-mastery. That's always been my goal.

I was joking. I used my very first emoticon to emphasise it.

I in no way think that Captain Black was wrong, especially since the answers would be so easy to find.
