The Properties And Applications Of Circles In Math: Diameter, Circumference, Area, And Tangent

Circle

Set of all points that are equidistant from a given point

a circle is a two-dimensional shape that is defined as the set of all points in a plane that are at a fixed distance (called the radius) from a given point in the plane (called the center of the circle). The distance from the center of the circle to any point on the circle is always equal to the radius.

Circles are often used in geometry because of their symmetry and the ease with which their properties can be calculated. They are used to solve problems in fields such as trigonometry, calculus, and physics.

Some of the properties of circles include:

Diameter: A diameter of a circle is a line segment that passes through the center of the circle and has its endpoints on the circle. The diameter is twice the radius.

Circumference: The circumference of a circle is the distance around the circle. It is equal to 2π times the radius, where π is the mathematical constant pi (approximately 3.14159).

Area: The area of a circle is the amount of space enclosed by the circle. It is equal to π times the radius squared.

Tangent: A tangent of a circle is a line that intersects the circle at exactly one point. The point of intersection is called the point of tangency.

Circles are used in many real-world applications, such as designing wheels for vehicles, calculating the area of circular fields or gardens, and determining the length of curved objects.
