Answer: The circumference of the circle is 53.38 cm.
Step-by-step explanation:
Circumference of the circle is the distance around the circle.
Formula used:

Where,
C is circumference of circle
r is radius of circle
Given:
Radius of circle = 8.5 cm
Now putting all the given values in the above formula, we get:

Therefore, the circumference of the circle is 53.38 cm.
 
        
             
        
        
        
Answer:
x>4
Step-by-step explanation:
 
        
                    
             
        
        
        
It has a constant rate of change
        
             
        
        
        
2 + 7 - 9 + 11
= 9 - 9 + 11
= 0+ 11
= 11

Using the geometric mean concept, it is found that the value of a is 18.
----------------------
The geometric mean, of a data-set of n elements,  , is given by:
, is given by:
![G = \sqrt[n]{n_1 \times n_2 \times ... \times n_n}](https://tex.z-dn.net/?f=G%20%3D%20%5Csqrt%5Bn%5D%7Bn_1%20%5Ctimes%20n_2%20%5Ctimes%20...%20%5Ctimes%20n_n%7D)
That is, the nth root of the multiplication of all elements.
----------------------
In this question:
- Two elements(n = 2), a and 34.
 
Thus:

We find the square of each side, so:


Simplifying both sides by 17:



The value of a is 18.
