Definition of a circle in math
WebA circle can be defined as the shape created when a plane intersects a cone at right angles to the cone's axis. It is one of the four conic sections. ellipse, parabola and hyperbola). In the above figure, there is a plane* that cuts through a cone. A circleis formed at the intersection of the cone and the plane if the plane is at right angles WebRadius definition, a straight line extending from the center of a circle or sphere to the circumference or surface: The radius of a circle is half the diameter.
