Answer:
4/11
Step-by-step explanation:
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
     = ( 1 - -3)/(7 - -4)
      = (1+3)/(7+4)
     = 4/11
 
        
             
        
        
        
That would be 4/6, or 2/3 simplified. As a percent, that would be 66%.

Step-by-step explanation:
we know that
The circumference of the circular walkway is equal to

where
D is the diameter
we have

substitute


so
Divide the diameter by the circumference
