Answer:
r =2.9985yd
Step-by-step explanation:
Given that the circumference of a circle is 2 r
r
where r is the radius and  = 3.1415926....
 = 3.1415926....
You have
2 r = 18.84 yd
r = 18.84 yd
2(3.1415926)r = 18.84 yd
6.2831r = 18.84yd
divide through by 6.2831
r = 2.9985yd = aprox 3yds
 
        
             
        
        
        
Answer:
y=mx+b is the form to write this equation. M is the slope and B is the y intercept. therefore:
y=4x-9
