The general equation of a circle is expressed as

(x - h)^2 + (y - k)^2 = r^2

Where

h represents the x coordinate of the center of the circle.

k represents the y coordinate of the center of the circle.

r represents the radius of the circle.

From the information given,

h = 4

k = - 5

r = 7

Thus, the equation of the circle is

(x - 4)^2 + (y - - 5)^2 = 7^2

(x - 4)^2 + (y + 5)^2 = 49

The equation of the circle is

(x - 4)^2 + (y + 5)^2 = 49
