The correct option is (b) circle .
- The conic section formed by the cone and a plane parallel to its base is a circle.
- The surface of a right-regular cone and a plane parallel to the base of the cone cross to form the closed figure known as a circle.
- The ellipse, which we'll discuss next, is actually just a special instance of the circle.
What is conic?
- Any curve created by the intersection of a plane and a right circular cone is known in geometry as a conic section, sometimes known as a conic.
- The intersection can be a circle, an ellipse, a hyperbola, or a parabola, depending on the angle the plane makes with the cone.
What conic section is formed from slicing parallel to the base of the cone ?
- The resulting curve is a circle if the cone is cut in half parallel to the base.
- The curve is known as an ellipse if the cone is cut at a modest angle.
- The curve generated is known as a parabola if the slice is done parallel to the cone's edge.
