A cone is a three-dimensional geometric shape that narrows from a flat circular base to a single point called apex or vertex. In other words, a cone can be formed by joining an infinite number of slanting lines to the circumference of a circle from a single point called the vertex. The distance from the vertex of a cone to the centre point of the base is known as the height of the cone. The length of the cone from the vertex to the boundary of the circular base is known as the slanting height.
Examples of Cone in Real Life
1. Ice Cream Cone
An ice cream cone is one of the best examples of the conical objects present around us. One can easily visualise an infinite number of slanting lines joining the vertex or the base of the cone and the circumference of a circle or the top of the cone.
2. Party Hat
A party hat also known as a birthday cap is yet another example of the conical objects used in everyday life. Similarly, the witch hat is also conical in shape.
3. Christmas Tree
Christmas trees are a classic example of conical structures available in nature. Similarly, one can also visualise cone geometric shape by looking at other trees such as deodar, sugar pine, red spruce, etc.
4. Volcano
Volcanos are one of the prime examples of cone-shaped objects existing in nature. The lava escapes out from the apex or the vertex of a volcano.
5. Top of a Rocket
The top of a Rocket or an airplane is designed in the shape of a cone. The conical shape of the top helps the vehicle to reject or minimize the air resistance and take-off smoothly.
6. Sharpened End of a Pencil
If you look at the tip of a properly sharpened pencil, you can easily visualise the conical geometric shape because it consists of a single vertex and a circular base.
7. Funnel
Funnels are yet another example of the common cone-shaped objects used in everyday life. The apex of the conical funnel is often attached to a cylindrical pipe that directs the flow of liquid and resists it from spilling.
8. Top of a Temple
The top of a temple also known as the ‘shikara’ or ‘shikhara’ is usually shaped like a cone. Hence, it forms a perfect example of conical objects present around us.
9. Loud Speaker
A loudspeaker is used to convert the electrical signal into sound signal. The front side of a loudspeaker is usually attached with a conical plastic cup. The conical shape of the cup helps the consumer to direct sound energy in a particular direction. Hence, a loudspeaker or a megaphone is a suitable example of cone-shaped objects used in everyday life.
10. Traffic Cone
Traffic cones are also known as pylons or road cones. They are usually orange in colour and are painted with broad white stripes. The purpose of a traffic cone placed on the road is to redirect the traffic to ensure safety and avoid any mishap.
