Answer: About 14.14 in^3

Explanation:

We know that the circumference of a sphere is C=2πr. We are given that the circumference is 9.42 in. We can find the radius to get our volume.


9.42=2\pi r


4.71=\pi r


r=1.5\\

Now that we know radius, we can find our volume.


V=(4)/(3) \pi r^3


V=(4)/(3) \pi (1.5)^3


V=14.14in^3
