Write the equation of a circle with a center at (-2, 3) and a radius of 4.

(x + 2)^2 + (y - 3)^2 = 4
(x - 2)^2 + (y + 3)^2 = 4
(x - 2)^2 + (y + 3)^2 = 16
(x + 2)^2 + (y - 3)^2 = 16

The equation of a circle:

Step-by-step explanation:

The equation of a circle:

(where the center is known as and the radius, known as ).

-Since you already have the center and the radius, use them for the equation of a circle:

Center:

Radius:

After you have the equation of a circle, simplify the radius by the exponent :

So, you have found the equation of a circle.
