WebAnswer : is a way to express the definition of a circle on the coordinate plane. The formula is ( x − h) 2 + ( y − k) 2 = r 2. h and k are the x and y coordinates of the center of the circle ( x − 9) 2 + ( y − 6) 2 = 100 is a circle centered at (9, 6) with a radius of 10 Diagrams Diagram 1 General Formula Diagram 2 WebGiven a circle with radius, r, centered at point (h, k), we can use the distance formula to find that: where (x, y) is any point on the circle. Squaring both sides of the equation, we get the equation of the circle: (x - h) 2 + (y - k) 2 = r 2. Notice that if the circle is centered at the origin, (0, 0), then both h and k in the equation above ...
