In geometry, a circle is a closed curve formed by a set of points on a plane that are the same distance from its center O. That distance is known as the radius of the circle. Diameter. The diameter of a circle is a line segment that passes through the center of the circle and has its endpoints on the circle. All the diameters of the same circle ...

The Circle in Standard Form. A circle 8 is the set of points in a plane that lie a fixed distance, called the radius 9, from any point, called the center.The diameter 10 is the length of a line segment passing through the center whose endpoints are on the circle.
A circle is usually named for its center. The circle in Figure \(\PageIndex{2}\) is called circle \(O\). A chord is a line segment joining two points on a circle. In Figure \(\PageIndex{2}\), \(DE\) is a chord. A diameter is a chord which passes through the center. \(BC is a diameter.
Aug 24, 2023 · Here’s an example: The circle below has a radius of 25mm. To find the area, we would plug the right numbers into the formula, like this: A = 3.14 x 252. 25 mm x 25 mm = 625 mm. 625 mm x 3.14 = 1,963 mm. 1,963 mm = 3.14 x 252. Understanding what a circle is and how to find its area is foundational to understanding more advanced mathematics ...
Diameter — a special chord that passes through the centre of the circle. A diameter is a straight line segment from one point on the circumference to another point on the circumference that passes through the centre of the circle. Segment — part of the circle that is cut off by a chord. A chord divides a circle into two segments.

A circle is named by the point at its center, so this circle would be called Circle A. When two radii (the plural of radius) are put together to form a line segment across the circle, you have a diameter. The diameter of a circle passes through the center of the circle and has its endpoints on the circle itself.
