Which is an equation of a circle with the center (-5, -7) and radius 6?

A.) (x - 5)^2 + (y - 7)^2 = 6

B.) (x + 7)^2 + (y + 5)^2 = 36

C.) (x + 5)^2 + (y + 7)^2 = 6

D.) (x + 5)^2 + (y + 7)^2 = 36

Step-by-step explanation:

_______________________________________________________

Note : a circle with center (a , b) and radius r has an equation of the form:

(x - a)² + (y - b)² = r²

_______________________________________________________

and according to the provided informations

a = -5

b = -7

r = 6

therefore

the equation of the circle is :
