Answer:

269 in³

Step-by-step explanation:

The formula for the volume of a sphere is V = (4/3)πr³.

Here the ball (sphere) diameter is 8 in, meaning that the radius is 4 in.

Thus, the volume of this ball is:

V = (4/3)π(4 in)³

If an "estimate" is good enough, use 3.14 for π:

V = (4/3)(3.14)(4 in)³ = 269 in³
