What is the equation of the circle with center (3, 4) and radius 5?
Correct: A
The general equation of a circle with center (h, k) and radius r is (x - h)^2 + (y - k)^2 = r^2. In this case, the center is (3, 4) and the radius is 5. Substituting these values into the equation gives (x - 3)^2 + (y - 4)^2 = 5^2, which simplifies to (x - 3)^2 + (y - 4)^2 = 25.
