Answer :

Looking at the image, the diameter of the sphere is equal to 6 ft.

Since the radius is half the diameter, the radius is equal to 3 ft.

Now, using r = 3 in the volume formula, we have:

[tex]\begin{gathered} V=\frac{4}{3}\pi r^3 \\ V=\frac{4}{3}\cdot3\cdot3^3 \\ V=108\text{ ft}^3 \end{gathered}[/tex]

Therefore the sphere volume is 108 ft³.
