Standard form for a equation of a circle with a center (4,-5) and a radius of 3

Answer: (x-4) 2 + (y+5) 2=9

Step-by-step explanation: The standard form for the equation oif a circle is

(x-a) 2 + (y-b) 2=r2

And in your particular case:

(x-4) 2 + (y--5) 2=32

(x-4) 2 + (y+5) 2=32

(x-4) 2 + (y+5) 2=9
