Respuesta :

if the "diameter" of the sphere is 28 cm, then the radius is half that, or r =14 cm, therefore

[tex]\bf \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}\qquad \boxed{r=14}\qquad V=\cfrac{4\cdot \pi \cdot 14^3}{3}\implies V=\cfrac{10976\pi }{3}[/tex]

Answer:

11488.21 cm³

Step-by-step explanation:

The formula for the volume of a sphere is

[tex]V=\frac{4}{3}\pi r^3[/tex]

The diameter is 28; this means the radius is 28/2 = 14.  Using 3.14 for π, we have

V = 4/3(3.14)(14³) = 11488.21
