Answer:
11488 ft³
Explanation:
diameter of sphere, d = 28 ft
radius of the sphere = half of the diameter = 14 ft
The volume of sphere is given by
[tex]V = \frac{4}{3}\pi r^{3}[/tex]
where, r is the radius of the sphere
By substituting the values
[tex]V = \frac{4}{3}\times 3.14 \times 14\times 14\times 14[/tex]
V = 11488.2 ft³
V = 11488 ft³
Thus, the volume of the sphere is 11488 ft³.
