The volume of a sphere is defined as: 
V=(4*pi*r^3)/3 
then, if we double the radius of the sphere (r=2r): 
V=(4*pi*(2r)^3)/3 
V=(4*pi*(2^3*r^3))/3 
V=(4*pi*r^3)/3*8 
Then, the answer is that if you double the radius of the sphere, its volume is increased 8 times. 
        
             
        
        
        
Answer:
32x-8y-3
Step-by-step explanation:
4(8x-2y)-3
4 x 8x = 32x
4 x 2y = -8y
