The equation of the circle whose center is at (4.4) and whose radius is 5 is

(x-4) ^2 + (y-4) ^2=25

Step-by-step explanation:

the standard equation of a circle is (x-h) ^2 + (y-k) ^2=r^2 where (h, k) are the coordinates of the center and r is the radius. In your case, just plug your the numbers into the equation
