Y=3 
to solve this you just substitute 4 in for x into the equation and solve for y. since negative 3 plus 7 is 4, y=4
        
                    
             
        
        
        
Answer:
 cubic inches
 cubic inches
Step-by-step explanation:
Diameter is increasing at 3 inches more than time, When t = 3
Diameter (d) = 3+3 = 6
d = 6
Radius is HALF of diameter, so
r = 6/2 = 3
Now, the volume of a sphere is given by the formula:

Putting r = 3, we get:

The volume would be 36π
 
        
             
        
        
        
373 as a fraction is 373/1000 but it needs simpliflying
