Answer:
<em>Okay, so what I think you mean to ask what the scale factor between the model and actual building</em> is, so i crunched the numbers. if 1 in equaled 8 feet and the actual thing was 64 ft, then we can just say that 64 divided by 12 is 5.3, so the model could be 
5.3 ft. is the size of the model
BUT
you said how many feet are they apart so in inches its 705, in ft its 58.75
Step-by-step explanation:
a foot is 12 in. 
64/12 is 5.3
64 ft is 768 inches, and 5.3 is 63. 
768-63 = 705.
there are 705 inches in difference, in feet its 58.75
 
        
             
        
        
        
Circumference is π*diameter. since we're given a diameter of 14, the circumference is 14π
