A sphere has a radius of 4 in. Which equation finds the volume of the sphere?

Answer:
[tex]V=\frac{4}{3}\pi (4)^3[/tex]
A is the correct option.
Step-by-step explanation:
The radius of the sphere is 4 inches.
Hence, r = 4
The volume of the sphere is given by
[tex]V=\frac{4}{3}\pi r^3[/tex]
Substituting the value of r in the formula, we get
[tex]V=\frac{4}{3}\pi (4)^3[/tex]
Therefore, we can say that the equation for the volume of the sphere is
[tex]V=\frac{4}{3}\pi (4)^3[/tex]
A is the correct option.
