Answer:
12.4 cm
Step-by-step explanation:
Use the sphere volume formula, V = 
 r³
r³
Plug in the volume and solve for r, the radius:
V = 
 r³
r³
7961 = 
 r³
r³
1900.55 = r³
12.39 = r
So, the radius of the sphere is approximately 12.4 cm
 
        
             
        
        
        
So close! But instead of adding the multiplication sign after the number you need to add them before. Good job though! :)
