I am assuming that the 100th flower pot lies on point D. That is each line occupies the points (l,r) where l is the number of the line (from left to right) and r occupies all the reals (so the line actually exists for all points up and down). The vertical lines can also be interpreted in the same way. Where n is the number of flower pot (counting from the bottom upwards). Then we can interpret the location of each flower pot as the point (0,n). I am assuming that the first flower pot is located 1m higher than point A. The circular shape of a giant wheel amusement ride can be easily observed.Ī compact disc or a CD is a device used to store the data in digital format.
Hence, roundabouts are a classic example of circle geometric figure present around us.Ī giant wheel or a Ferris wheel is one of the major attractions of a carnival. If you take a complete turn around a roundabout, you can trace its boundary that is circular in shape. It can be noted easily that not just the outer boundary of a dartboard represents a circle, but even the inner rings are concentric circles. Hence, the wall clocks, table clocks, and wrist-watches are the chief examples of circular-shaped objects used in real life.ĭartboards are circular in shape. The most preferred shape of a clock is the circular shape. So next time when you grab a bite of any such food items, get yourself reminded of the definition and terms related to the geometric figure circle.īuttons are available in a number of fancy shapes, but the most popular amongst them are the circle-shaped buttons. Hence, it is one of the best examples of circular shaped objects used in real life.Ĭookies, cakes, doughnuts, pancakes, pizzas, and many other eatables are circular in shape. It is used to store and play audio information. The circle shape of the hula hoop can be very easily observed.Ī vinyl record or a gramophone record is a disc that consists of modulated groovings. Hence, they are a prominent example of circle geometric shape present in real life.Ī hula hoop is a toy that is swirled by a person around his/her waist, arms, or limbs for amusement and fitness purposes. The coins possess a perfectly round and circular structure. The tyres of a vehicle are yet another example of the circle-shaped objects used in day to day life. For instance, rings, bracelets, earrings, bangles, etc., all constitute a perfect example of circle-shaped objects. If you observe the structure of the hub, you can easily observe the circle geometric figure.Ī number of ornaments that we wear are circular in shape. The wings of a fan are connected to a hub. Hence, a dish or a plate is the most common example of the circular shaped objects used in everyday life. Most of the dishes used to serve food are circular in shape.
TangentĪ line touching the circle at one point is known as a tangent. SecantĪ line touching the two boundary points of a circle is known as a secant. The larger area enclosed between the chord and the arc is known as the major segment, while the smaller area represents the minor segment.
The area formed by joining the endpoints of an arc with the help of a chord is known as a segment.
The smaller area formed between the arc and the two radii is known as the minor sector, whereas the larger area formed is known as the major sector. The area formed by joining the endpoints of the arc to the centre is known as a sector. ChordĪ straight line segment joining the two points lying on the boundary of the circle is known as a chord. The shorter distance between the two points signifies the minor arc, whereas the larger distance represents the major arc. The line joining the two points present on the boundary of the circle is known as an arc. The diameter is twice the magnitude of the radius of a circle. The line that joins the two boundary points of a circle and passes through the centre is known as the diameter. The fixed distance from the centre to the outer boundary of the circle is known as radius. The fixed point situated in the middle of the circle is known as the centre.
