WebApr 27, 2024 · Well, we already know the center of the circle, so we can plug it into the equation to get: (x + 6)^2 + (y - 5)^2 = r^2. To find the radius, we need to find the distance from the center of the circle to a point on the circle. They give us a point on the circle so, by using the distance formula: d = root[(-11 + 6)^2 + (3 - 5)^2] d = root[25 + 4] WebFeb 22, 2024 · Then substitute with the given center (5,6) to the standard equation form of a circle.
