The equation of a circle is
what are the coordinates for the center of the circle and the length of the radius

The answer is

Step-by-step explanation:

The general equation of a circle is given by

where the center of the center of the circle is given by

From the question the equation is

x² + y² + 14x + 2y + 14 = 0

Comparing with the general equation above we have

2g = 14 2f = 2

g = 7 f = 1 c = 14

So the center of the circle is

The radius of a circle is given by

where

g = 7

f = 1

c = 14

Substitute the values into the above formula

That's

we have the final answer as
