Arc length:  s = radius (central angle)
Here, 18 cm  = (radius)(7pi/8)
Solving for the radius:
                  18 cm          (18 cm)(8)
radius = --------------- = ------------------ = ?  Please calculate this.
                 (7pi/8)                7pi

Answer:
20%
Step-by-step explanation:
We can start by looking at it as a ratio, so 4 divided by 20 and 4/20 = 0.2, so that would be 20% viewing 1=100%.
Another way is
20 here is 100%, and for 20 to equal 100, we have to multiply it by 5. To balance it out, multiply the top by 5 as well, and 4 * 5 =20. Therefore, 4/20 = 20%
 
        
             
        
        
        
Could it be 12? Difference between 16-13=3, 13-7=6. 4-3=1, 3-1=2. Seems as if for each column, difference between first and second row is one half the difference between the 2nd and third rows
