Using the thechnique of multiple intergration prove that the volume of a sphere is 4/3 Pi r^3.
The Attempt at a Solution
Equation for sphere is x^2 + y^2 + z^2 = r^2
Do I solve it using for example z = root(r^2 - x^2 - y^2)
Or is it best do solve it using angle such as y=r sin (Theta)
I hope this makes sence.
