5 BEST REAL LIFE APPLICATIONS OF CIRCLES.

As you probably know that “A Circle is the collection of all the points in a plan which are always equidistant from a fixed point.” But, have you ever thought what could be the Real World Applications of Circles?

Circles are used in many real-world applications. In this Post you are going to learn about 5 Best Real Life Applications of Circles. So let’s dig in.

1.) In Construction Purpose –

All manholes are round so that their covers never slip through the pipes from the ground to the sewers. Any way you turn the cover it is impossible to force it through the hole, since the distance from the centre of the circle is always the same. Since polygons do not hold this property, a circle is very useful for this purpose.

2.) In Vehicle Wheels for A Smooth Motion –

Circular wheels allow the opportunity for constant and smooth motion when riding a bicycle or automobile. If the circle had edges or vertices the ride would become very bumpy, because the distance from the centre of the wheel to its perimeter would no longer be constant. In addition, a car will travel the distance its wheels rotate, because the friction between the wheel and pavement cause the car to move. For every revolution the tires make, the car will travel the length of the circumference of them. If a wheel has a diameter of 32 inches, then its circumference, or distance around, is 32π inches ≈ 100.5 inches.

3.) In Automobile Devices –

In addition to distance travelled by an automobile, the circumference of circles is used in several applications. A trundle wheel is a device used to measure distances that are too long for a tape measure. A marking is placed on the wheel so that it clicks for one complete revolution. A trundle wheel can be made in any size, although it is convenient to make one with a diameter of 31.8 cm, because then its circumference will be 1 meter (circumference is the product of π and the diameter of the circle). Therefore, as you push the trundle wheel, every click that is recorded on the odometer means that the wheel has gone around once and you have traveled 1 meter.

4.) To Determine the Price of Circular Food –

The area of a circle is useful to determine the price of circular foods that have the same height.

For example, pizzas are often advertised according to their diameter. A pizza with a diameter of 12 inches might sell for 220 rupees, and a pizza with a diameter of 16 inches for 370 rupees. Is that a reasonable deal? Since the amount of pizza is related to its area, it would be more beneficial if the consumer were told the unit cost of the pizza per square inch. Instead, consumers may develop a misconception and think that the 16-inch pizza should be 16/12, or 4/3, as much as the 12-inch pizza.

In the 12-inch pizza, the radius is 6 inches. So the area of the pizza is π(6)² ≈ 113.1 square inches. At a sale price of 220 rupees, the consumer is paying about 1.94 rupees per square inch of pizza. In the 16-inch pizza, the radius is 8 inches. So the area of the pizza is π(8)² ≈ 201.1 square inches. At a sale price of 370 rupees, the consumer is paying about 1.83 rupees per square inch of pizza. At first glance, one might think the 12-inch pizza is a better buy, but actually it is the other way around. Since volume purchases usually have a cheaper unit price, these prices seem pretty reasonable. Is this true about the prices at your favourite pizza shop?

5.) To Make the Household Stuff –

A circle is a figure that has an optimal area based on its perimeter. Based on a given perimeter, there is not another shape that has an area greater than a circle. Similarly, based on a given area, there is not another shape that has a smaller perimeter than a circle. In essence, this information indicates that a great way to make use of materials and space is to form circles. Think about all the objects made of raw materials that are shaped into circles, such as plates, cups, pots, compact discs, and digital video discs. All of these objects are designed to hold substances or information that take up space in a resourceful way.

All materials are not designed to include circles, however, because a circle does not necessarily serve all functions. For example, a book is shaped like a rectangular prism instead of a cylinder, because it may be easier to store on a shelf and retrieved easily with its visible binding.
