Write the equation of a circle with a center at (-2,-10) and a radius of 1.2.
MrRissso [65]

Answer:

The correct option is the letter "C", (x + 2)^2 + (y + 10)^2 = 1.44.

Step-by-step explanation:

The standard form for a circle's equation has the following structure:

(x - x_c)^2 + (y - y_c)^2 = r^2

Where (x_c,y_c) are the coordinates of the center of the circle and r is the radius. Applying the data from the problem we have:

(x - x_c)^2 + (y - y_c)^2 = r^2\\\[[x - (-2)]^2+ [y - (-10)]^2 = (1.2)^2\\(x + 2)^2 + (y + 10)^2 = 1.44

Therefore the correct answer is the letter "C", (x + 2)^2 + (y + 10)^2 = 1.44.
