Write the equation of a circle with a center at (-2,-10) and a radius of 1.2.
A)(x + 2)2 + (y + 10)2 =1.2
B)(x - 2)2 + (y - 10)2 = 1.2
C)(x + 2)2 + (y + 10)2 = 1.44
D)(x + 2)2 + (y + 10)2 = 14.4

.
are the coordinates of the center of the circle and 
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](/tpl/images/0676/5051/87c45.png)
