Answer: The answer is (C) 36π cubic inches.
Step-by-step explanation: We are given to find the volume of a sphere with radius 3 inches.
We know that the volume of a sphere with radius 'r' units is given by
[tex]V=\dfrac{4}{3}\pi r^3.[/tex]
Here, we have,
radius, r = 3 inches.
Therefore, the volume of the sphere is given by
[tex]V\\\\=\dfrac{4}{3}\pi r^3\\\\=\dfrac{4}{3}\pi \times 3^3\\\\=\dfrac{4}{3}\pi \times 27\\\\=36\pi~\textup{cubic inches}.[/tex]
Thus, (C) is the correct option.
