Answer:
r=8
Step-by-step explanation:
Given formula:
r = C / 2π
It is given that C = 16π
hence
 r = 16π / 2π = 8
 
        
             
        
        
        
For this case we have an equation of the form:
 
 Where,
 h0: initial height
 v0: initial speed
 a: acceleration
 Substituting values we have: 

 Rewriting we have:
