Choose the correct conic section to fit the equation.
yanalaym [24]

Answer:

Option A) Circle.

Step-by-step explanation:

We are given the equation:

(x - 3)^2 + (y - 12)^2 = 25

A general equation of the circle is of the form:

(x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center of the circle and r is the radius of circle.

Comparing the two equations, we get,

(h,k) = (3,12)\\r = \sqrt{25} = 5

Thus, the given equation is equation of a circle centered at (3,12) and of radius 5 units.
