20. what is the standard form of the equation of the circle in the graph?

x2 + (y + 4)2 = 16

x2 + (y − 4)2 = 16

x2 + (y + 4)2 = 4

x2 + (y − 4)2 = 4

Option 3

Step-by-step explanation:

The equation of a circle has the following standard form

Where the point (a, b) is the center of the circle and r is the radius.

In the circumference it can be seen that the center is at the point (0, -4) and the radius r = 2.

Therefore the equation of the circumference is:

Finally the equation is:
