Answer:
321.6 in³
Step-by-step explanation:
You want the volume of a bowling ball 8.5 inches in diameter.
The volume of a sphere can be computed from ...
[tex]V=\dfrac{\pi}{6}d^{\,3}[/tex]
Using the given diameter, we find the volume to be ...
[tex]V=\dfrac{\pi}{6}(8.5\text{ in})^3\approx 321.6\text{ in}^3[/tex]
The volume of the bowling ball is about 321.6 cubic inches.

Additional comment
When the given dimension is the diameter, we find it convenient to use the volume formula that is a function of diameter. One usually sees the sphere volume formula as V = 4/3πr³. Using r=d/2 gives the above formula.
