What is the equation of the circle with center (2, 3) and radius 4?
Correct: A
The general equation of a circle is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius. Given the center (2, 3) and radius 4, we can plug in the values: (x - 2)^2 + (y - 3)^2 = 4^2, (x - 2)^2 + (y - 3)^2 = 16.
