The equation of a circle is (x + 6)2 + (y - 1)2 = 12. determine the coordinates of the center of the circle.
center (-1, 6)
center (1, -6)
center (-6, 1)
center (6, -1)

The correct answer is third (-6, 1)

Step-by-step explanation:

Given:

(x + 6)² + (y - 1)² = 12

The equation of a circle in the canonical form from which you can directly determine coordinates of the center is:

(x - p)² + (y - q)² = r² where p(x -axis) and q (y-axis) are coordinates of a circle.

p = - 6 and q = 1  => ( -6, 1)

God with you!!!

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
