Nice 
area=pir^2
the areas are
pir^2+pi(2r)^2
they add to 8pi
8pi=pir^2+pi(2r)^2
undistribute pi
8pi=pi(r^2+(2r)^2)
divide both sides by pi
8=r^2+(2r)^2
expand
8=r^2+4r^2
add
8=5r^2
divide by 5
8/5=r^2
sqrt both sides
√(8/5)=r
double since it is double
2√(8/5) is radius of bigger aka (4√10)/5
radius=(4√10)/5
        
             
        
        
        
It would be 2/3 because you have to minus 2x on to the other side then you do-3 to -6 and -2x and you would get for your Y INTERCEPT would be 2/3
        
                    
             
        
        
        
The diameter is 18.8 feet
I believe the circumference is 59.0 feet
