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 ... WebThe standard equation for a circle centred at (h,k) with radius r. is (x-h)^2 + (y-k)^2 = r^2. So your equation starts as ( x + 1 )^2 + ( y + 7 )^2 = r^2. Next, substitute the values of the given point (2 for x and 11 for y), getting. 3^2 + 18^2 = r^2, so r^2 = 333. The final equation is …
