Steven's expression is relatively simple, but I can see why it might be
confusing to someone who isn't mathematically minded, expecially when it's
written in ASCII. I'll try and explain for you. Firstly, this is the
relationship: v = (1/6)*pi*d^3. v is the volume of the sphere, pi is a
Greek letter that is used to reprecesnt a particaulary special constant
(equal 3.141592654 to ten sig. fig.) and d is the diameter of the sphere.
The symbol ^ means "rasied to the power of", so d^3 is "d to the third
power" or "d cubed", and * means "multiplied by". So, what you have to do
is cube the diameter, and multiply it by some constant factors. When I say
cube the diameter, I mean multiply it by itself twice, so d*d*d = d^3, if
No wonder physicists have a bad name. Some of you lot are such grumpy
*!>,.,?!** I think you sometimes forget that even "Simple" algebra is very
difficult for many people. To suddenly jump the way you lot did...
If I taught my AS/A2 lot that way half of them wouldn't have a chance - we
need to encourage not make it harder by being arrogant....
Sorry, but there you are!
