Answer:
![V=(4)/(3)\pi (4)^3](https://img.qammunity.org/2019/formulas/mathematics/middle-school/eiadnfg34l6g161vmx1rm3435kg5w1fvh5.png)
A is the correct option.
Explanation:
The radius of the sphere is 4 inches.
Hence, r = 4
The volume of the sphere is given by
![V=(4)/(3)\pi r^3](https://img.qammunity.org/2019/formulas/mathematics/high-school/gesu7zoklmpef44yb3hxm2uqvc14lb3vl6.png)
Substituting the value of r in the formula, we get
![V=(4)/(3)\pi (4)^3](https://img.qammunity.org/2019/formulas/mathematics/middle-school/eiadnfg34l6g161vmx1rm3435kg5w1fvh5.png)
Therefore, we can say that the equation for the volume of the sphere is
![V=(4)/(3)\pi (4)^3](https://img.qammunity.org/2019/formulas/mathematics/middle-school/eiadnfg34l6g161vmx1rm3435kg5w1fvh5.png)
A is the correct option.
