The standard form of the circle equation is:  (x - x0)2 + (y - y0)2 = r2 , where the coordinates of the centre are (x0, y0) and the radius is r.

 

Adele Acres: Since this is at the origin x0 = 0 and y0 = 0 and we are told r = 4.

 

Brown Lake:  5 miles east of the origin means x0 = 5; 4 miles north means y0 = 4; we are told r = 3.

 

Cady City:  4 miles east means x0 = 4; 4 miles south means y0 = -4  (note that it is negative);  we are told r = 5.

 

Can you take it from  here?
