Apc.3.1.8 difference in sphere volume

Terrible question. Maybe the best LINEAR approximation? Or words to that effect.

$$\dfrac{4}{3}\pi(3.1)^3-\dfrac{4}{3}\pi (3)^3$$

Are you studying geometry or calculus? You don't seem to have used any calculus.

Please read up on "differential". You'll need some sort of partial derivative.

it was originally from barrons but couldn't find it

Ill delete it

Why not learn from it.

Start with $$V = \dfrac{4}{3}\pi r^{3}$$

Calculate $$\dfrac{dV}{dr}$$

Okay, so it's not a "partial" derivative.
