A.0 I don't actually know
        
             
        
        
        
61 because you always multiply first 60 x 0= 0 so now we have 60+1 which is 61
        
                    
             
        
        
        
Y = 7  
Explication pas à pas:
 x est -3 donc -3 et connectez le x.
Y = -1 / 3 (-3) +5.
Y = 1 + 5
Y = 7 
 
        
             
        
        
        
Answer:
Solution given;
for sphere
radius [r]:12inches
another 
radius [R]:9inches
Now 
difference in volume of sphere:
volume of sphere of having radius [r-R]
= -
-
= (12³-9³)
(12³-9³)
= 1332π cubic inches 
The volume of the larger sphere is <u>___1332</u>__π cubic inches greater than the volume of the smaller sphere.
