Geometry circles formulas
WebA circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.Equivalently, it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.The distance between any point of the circle and the centre is called the radius.Usually, the radius is required to be a … Weba = π r 2. The dog’s leash represents the radius of the circle, because the dog can run 9 feet in any straight line from the center of the stake in the ground. So we must find the area of the circle using 3.14 for π and 9 for …
