The center of the circle is at (1, 3) and the radius is 4. What is the equation of the circle in standard form?

(x - 1) ^2 + (y - 3) ^2 = 4^2

Step-by-step explanation:

The generic equation of a circle in standard form is:

(x - h) ^2 + (y - k) ^2 = r^2, where the center is (h, k) and the radius is r.

Taking the given info, we then have:

(x - 1) ^2 + (y - 3) ^2 = 4^2
