The volume of a sphere can be found by the formula:
volume = 4/3 π r3

nincompoop · Answer

well now, why is that?

anonymous · Answer

that's my question... why is 4/3 there...pi is probably there because it's there for most circular formulas... and why is r cubed?

Okay so now we know where to work from. This is the equation: V = 4/3 π r3 . In this equation, "V" represents volume and "r" represents the radius of the sphere. This distance "r" is known as the radius of the sphere, and the given point is known as the center of the sphere. http://en.wikipedia.org/wiki/Sphere This will also give you a clear understanding. Zale's video can also be very helpful as well.
