A circle is described by the equation (x−12)2+(y−32)2=49. What are the cordinates for the center of the circle and the length of the radius?
(-12,-32), 23units
The equation of a circle is (x - a)² + (y - b)² = r², where the coordinates of the center(C) are C(a,b) and "r" the radius. Here, C(12, 32) and r=7 if you need, so there is no correct alternative.
