Answer:
They have a scale factor of 2
They are both the same shape
The big circle has a radius of 4 and the small circle has a radius of 2. You divide the bigger circle by the smaller circle. 4/2=2

Answer:
Matt ;
Used diameter of the ball instead of Radius 
Step-by-step explanation:
The volume of a sphere is given as :
4/3πr³
Radius, r = diameter / 2
Given that, the diameter = 15 cm ; The Radius = 15 / 2 = 7.5 cm
Matt made an error in his calculation by failing to covert the value of the diameter given to Radius. 
By dividing the diameter by 2 = 15 / 2 = 7.5, we obtain the Radius, which is what Billy did in her own calculation. 
 
        
             
        
        
        
I think the answer would be 44,000,000 because if you roundthe 951 it goes to 1,000
