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 circumference of a circle is calculated by multiplying the diameter by pi.Ok. The area of a circle is pi times the radius squared. The fixed point is called the circle’s centre, and the distance between the border points and the centre is called the radius. ConclusionĪ circle is a two-dimensional plane geometric figure produced by connecting an endless number of equidistant points around a fixed point. FormulasĪ circle has only an area – πr 2 however, a sphere has a three-dimensional figure (object) with an area – 4πr 2 and a volume – (4/3)πr 3. Simply put, a circle is a round object in a plane, whereas a sphere is a round thing in space. On the other hand, a sphere is the locus of a point that is at a constant distance from a fixed point in three-dimensional space. The centre of a circle is the fixed point, and the distance between these two locations is the radius. Every point on this curved line is the same distance from the circle’s focal point (centre). Although there is no real-world example of a circle because there is no such thing as a zero-width item, various objects are spherical in shapes, such as tennis balls, planets, oranges, and globes.Ī closed curving line is referred to as a circle. Naturally, the circle and the sphere are two figures that we see all the time. Equal circles have the same area as well as the same circumferenceĬommon examples of circular-shaped items include dishes, buckets, ornaments, the centres of fans, coins, tyres, hula hoops, buttons, mechanical watches, and dartboards, to name a few.The radii of equal or identical circles are equal.Angles comparable to arcs of the same circle are proportionate.The radii of two or more different circles are proportionate to their circumferences.If two tangents share a point of origin, they are equal.The radius always forms a 90° angle (right angle) with the tangent line.If two or more chords are all equidistant from the centre of a circle, they are equal in length.The chord of a circle is bisected by its radius, which is perpendicular to it.All circles are comparable, regardless of the size of their radii or diameters.A circle’s outer line is equidistant from its centre.The diameter of a circle divides it into two equal halves.A circle’s diameter is equal to its radius divided by two.The diameter of a circle equals the length of its longest chord.Congruent circles have equal radii or diameters.There are many interesting characteristics of circles, such as: Many domestic products have circles in their designs, such as cups, candles, and doorknobs. Ferris wheels raise the circle to vertical heights at amusement parks and carnivals.

The bases of mushrooms with domed tops are round. The Manicouagan Reservoir in Canada is a ring-shaped lake that arose from the crater’s remains. Circles can be easily found in natural and artificial things in everyday life. A circular-faced object, such as a dinner plate, a soda can, a traffic cone, or a circular flower bed in a garden, is designed considering the concept of the circle area. The circle is nearly unavoidable in the work of artists and painters. The symmetrical qualities of the circle are frequently used by architects when designing sports tracks, recreational parks, buildings, roundabouts, Ferris wheels, and other structures. Mathematicians studied circles, which helped them develop calculus and astronomy. As there was no idea of 3D shapes, people assumed that the moon, sun, and other planets were circular. The circle has a long and illustrious history. A circle should never be confused with a polygon because it is made up of curves instead of straight lines. A circle is a perfectly round or closed, two-dimensional geometrical shape described as a set of all points in the plane equidistant from a particular central point. The term “circle” comes from the Latin word circus, which means hoop or ring.
