VOLUME OF A CONE FORMULA

A cone is a three dimensional geometric shape that tapers smoothly from a flat, usually circular base to a point called the apex or vertex. it is the solid figure bounded by a plane base and the surface formed by the locus of all straight line segments joining the apex to the perimeter of the base.

The volume of a cone formula is as follows:-


Volume = 1/3Πr2h


Right Cone: A right cone is a cone in which the vertex is aligned directly above the center of the base. The base need not be a circle here.

A pyramid with a circular base. If the point (vertex) is directly above the centre of the circle, it is known as a right circular cone. A right circular cone is generated by rotating an isosceles triangle about its lines of symmetry. The distance from the edge of the base of a cone to the vertex is called the slant height.

Oblique Cone:
When the vertex of a cone is not aligned directly above the center of its base, it is called an oblique cone
