Exponential growth functions are the functions that normally take the form 
y=ab^x
where:
a=initial value
b=growth rate
x=time
An example of situation that takes this form is the population growth of a particular group say and organism. 
        
             
        
        
        
Answer:
<h2>Yes the circumference is about times greater than their diameters</h2>
Step-by-step explanation:
We will approach this problem by doing a check
Say the diameter of a circle is 4 cm
Hence the radius is 3 cm
We know that the circumference is 

The circumference is about 3 time bigger than the diameter
Let us try another case say the diameter is 6 cm
The radius is 3 cm

 
        
             
        
        
        
The answer is 9 because you solve it from left to right and 3x5 equals 15, 15 subtracted by 6 equals 9
        
                    
             
        
        
        
14.52 - 5.8 = 8.72 bc math
        
                    
             
        
        
        
Answer: 190800
Step-by-step explanation:
10 • 10 = 100
Than when you multiply anything 100 you just add two 0s to the end. 
100 • 1908 = 190800
