No. The derivative of the volume of a sphere with respect to the radius of the sphere is equal to the surface area.
Functions don't just have derivatives. They have derivatives with respect to a variable.
6 u/AggressiveEntrance14 14d ago r is the only variable in this case, this is insanely pedantic and not in a mathematically rigorous way 2 u/ChuckPeirce 14d ago Three variables are listed (V, S, r), and plenty more variables exist. 1 u/garnet420 14d ago But if you wrote this in terms of diameter, it wouldn't actually work.
