right, i'm now stuck on bloody triple integrals!
To find the volume of a sphere (radius a) using triple integrals, must I do the following
integrate 1 with respect to x between limits +root(a^2-y^2-z^2) and -(same thing)
then integrate that with respect to y between limits root(a^2-z^2) and the negative of that
and then integrate THAT with respect to z between -a and a!?
it just seems very complex!
