Answer:

12.4 cm

Step-by-step explanation:

Use the sphere volume formula, V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³

Plug in the volume and solve for r, the radius:

V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³

7961 = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³

1900.55 = r³

12.39 = r

So, the radius of the sphere is approximately 12.4 cm
