Question

. Consider the circle with equation (x – 12)2+(y – 12)2=100. a) What is the center of this circle?

Answer 1

The equation of a circle is (x - h)² + (y - k)² = r²
(h, k) is the center of the circle
SO since h is 12 and k is 12, the center of the circle must be (12, 12)
For extra info, the radius is √100 so r = 10
