<span>A hemisphere is simply half a sphere, which means it has half of the volume of the original sphere. 
                                
             
                    
              
Answer: 
The volume of the sphere is eight times the volume of hemisphere
Step-by-step explanation: 
we know that
If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z-----> the scale factor
x-----> volume of the hemisphere
y-----> volume of the sphere
in this problem we have
substitute
that means------> The volume of the sphere is eight times the volume of hemisphere
