Step-by-step explanation:
 
Distance 
midpoint height  
let
Gradient  
      
Perpendicular Gradient 
midpoints  
Similar to perpendicular
Now I'll obtain the perpendicular bisector solution
An equation of the center circle radius will be
 radius will be .

2(10-3) distribute = 2*10 is 20 and 2*3 is 6
20-6+(5-14/2)
now 20-6 is 14
14+(5-14/2)
now 14/2 is 7
14+(5-7)
now 5-7 is -2
14+-2
is 12 
the answer is 12
but if you want to you can do 12/3 to get the greatest common factor 
which is 4
hope i help you :P
