C. A sphere with radius 0.6 inches.
Here is why:
The equation for the volume of a sphere is:
[tex]V=\frac{4}{3} \pi r^3[/tex]
We can plug in and solve.
[tex]V=\frac{4}{3}*\pi *0.6*0.6*0.6[/tex]
We will multiply everything but leave the 3 to divide later.
So...
[tex]4*\pi *0.6*0.6*0.6=0.864\pi[/tex]
Divide by 3.
[tex]0.864\pi /3=[/tex]
0.288π
