The cone is a three-dimensional geometric shape that generally appears in our everyday life, from birthday caps to ice cream cones. It is a unique geometric figure with a circular cross-section and a pointed top that serve as ideal characteristics for designing buildings and other objects. Understanding the concept of the surface area of cone is helpful in understanding various calculations based on determining the area of cones.
What is the Surface Area of a Cone?
The area occupied by the surface of a cone is called the surface area of a cone. It is a simple shape that can be created by stacking multiple triangles and rotating them around an axis. Since the base of a cone is a flat surface, we can find both the total surface area and a curved surface area of a cone. These cones can be classified as a right circular or an oblique cone. The vertex of a right circular cone is generally above the center of the base, on contrary the vertex of the cone in an oblique cone is not vertically above the center of the base. The applications of cones and their surface area are found in many spheres of our life. Here are some examples of applications of the surface area of a cone:
For Building Traffic Cones
Traffic cones are one of the most common applications of cones that can be found along highways and sidewalks throughout the world. These traffic cones were first invented in New York in the year 1914. Back then, these traffic cones were made up of concrete which eventually turned into the bright orange cones that we see nowadays. The circular base of these traffic cones provides stability to keep the cone upright.
Construction and Building
Teepees are cone-shaped structures also known as tipis. These were the traditional kind of houses made by the native Americans. These houses were built with wooden poles that were arranged in a cone shape structure. These wooden poles are tied to each other at the top and covered with animal skin or even clothes so that a hole is left at the top for the smoke to escape. Teepees were specifically helpful during the early native Americans’ times due to their convenience of portability. The concept of the surface area of a cone is helpful in designing these houses. The wide round base of such houses allows more people to stay inside them, while its pointed top provides a place for fire smoke to gather and exit the teepee.
During the old days, the turret of a castle was built to serve as a check post for soldiers. Before the sixteenth century, these turrets were made in squared shapes. As these round turrets were better and had no blind spots to leave soldiers vulnerable, it became a famous castle design since then.
The famous witch’s hat can be easily spotted in movies, cartoons, and on the heads of little trick-or-treaters on Halloween. These cone-shaped hats have been in use since as early as the seventeenth century, which means that this iconic hat has been around for a long time. In the past , these pointed hats were really popular among fashionable Londoners. Later this became a fashion and spread across to the countryside and remained there for a long time after it had faded in London.
Gaining an in-depth understanding of the area and volume of cone is highly important for every student as it forms the basis of understanding geometry and other math topics.
