Measurements of Cones

  • Introduction to Cone

    A cone is a solid figure generated by a line, one end of which is fixed and the other end describe a closed curve in a plane. A circular cone is a solid figure whose base is a circle and whose lateral surface area (i.e. curved surface area) tapers uniformly to a point: which is […]

  • Volume of a Cone

    The volume of a right circular cone is one-third of the volume of a right circular cylinder of the same base and same height.             If is the height of the cone, is the radius of the base, then                                                                (as area of base ) Rule: The volume of a cone equals […]

  • Curved Surface Area of a Cone

    If a perpendicular cut is made from a point on the circumference of the base to the vertex and the cone is opened out, a sector of a circle with radius is produced. Since, the circumference of the base of the cone is , therefore, the arc length of the sector of the circle is […]
