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), … WebExplore math with our beautiful, free online graphing calculator.

WebFirst you need to know that the equation for a circle is (x-a)^2 + (y-b)^2 = r^2 where the center is at point (a,b) and the radius is r. so for instance (x-2)^2 + (y-3)^2 = 4 would have the center at (2,3) and have a radius of 2 since 4 = 2^2. This means if you went a distance of 2 away from that center point you would be on the circle. WebA circle is all points in a plane that are a fixed distance from a given point on the plane. The given point is called the center, and the fixed distance is called the radius. The standard form of the equation of a circle with … canning duck band
