What is the center of the circle given by the equation (x - 3)2 (y - 9)2 16?
Well, honey, the center of that circle is simply the point (3, 9). You see, the equation you provided is in the form (x - h)² + (y - k)² = r², where (h, k) is the center of the circle. So, in this case, the center is at (3, 9). That's all there is to it, sugar.
Find the equation of a circle with center -2 and -4 and radius 3?
The equation for a circle is generally written in the form (x+a)^2+(y+b)^2 = r^2Remember, for the centres for the x and y value, they go in the opposite direction of the rule.So:if the centre is (-2,-4), the equation of the circle is (x+2)^2+(y+4)^2=9
