Answer:
The word ‘circle’ is derived from a Greek word that means ‘hoop’ or ‘ring.’ In geometry, a circle is defined as a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center.” The history of the circle is ancient. People used to believe that the moon, sun, and other planets are circular because there was no concept of 3D shapes—mathematicians study circles which helped them develop calculus and astronomy.
In 1700 BC, Rhind Papyrus proposed a method to find the area of a circle. At that time, the value of pi was not accurate. In 300 BC, Euclid stated the properties of circles in his book. Finally, in 1880 AD, a German mathematician, Lindemann, solved the issue with pi’s value and proved that pi is a transcendental (not a root of any polynomial with rational coefficients) number.

Step-by-step explanation:
Answer:
parts of a circle = tangent, chord, arc, segment, sector, diameter, radius, circumference.
A lot of jobs use area and perimeter such as; Surveying, flooring estimates architecture, mechanical engineering,
Typically, a land surveyor conducts and records a perimeter survey and part of this includes the transverse
Surveyors typically measure positions in series. Starting at control points, they measure angles and distances to new locations and use trigonometry to calculate positions in a plane coordinate system. Measuring a series of positions in this way is known as "running a traverse." A traverse that begins and ends at different locations is called an open traverse.
Here they create segments as seen below attached.
Engineers Drawing Circles: Begins by defining the radius, diameter and circumference and asking students to draw circles with a given radius, circumference or area. and when requiring they draw two circles with the same centre, one property of each circle being given in example with bridges, or arc of a circle working with calculating precise length for material lists.
The Annulus: the shape formed between two circles. They use the properties of the annulus by completing a table with values of pertaining to the properties of the inner circle, the outer circle and the annulus.
With sectors, engineers, can defining major and minor sector, they calculate the arc length and the area of a sector of a circle. They have learnt how to complete a table of values of properties of a circle and a sector of that circle given different properties from which to start with.
Architecture typically used series of circles in gothic architecture, but also art deco and earlier historic arches, use of semi-circular arches in architecture, and tangents are used as a .function to compute a building's height if they know their distance from the structure and the angle between their eyes and the building's top; clinometers can help them measure those angles.
Metal fabricators and product design workers use spring dividers help them inscribe an arc or create a circle pattern.
I would then write a little more about chords and radius
