There are many parts of a circle that make it a circle. A circle is a 2D shape and is measured in terms of its radius. The word ‘Circle’ is derived from the Greek word 'kirkos' meaning ‘ring’ or ‘hoop’. The parts of a circle include the radius, diameter, circumference, and so on.
There are two main "slices" of a circle: The "pizza" slice is called a Sector. And the Segment, which is cut from the circle by a "chord" (a line between two points on the circle). Try Them! Area of a Sector. You can work out the Area of a Sector by comparing its angle to the angle of a full circle. Note: we are using radians for the angles.
Based on the shape and position, there are different parts of a circle in geometry that can be listed as center, radius, circumference, diameter, chord, arc, segment, tangent, secant, and sector. It will be easy to identify and label parts of a circle using the diagram shown below. Recommended Games.
Definition. Circle: the set of all points on a plane that are a fixed distance from a center. Area. The area of a circle is π times the radius squared, which is written: A = π r 2. Where. A is the Area. r is the radius. To help you remember think "Pie Are Squared" (even though pies are usually round):
22 Ιουλ 2024 · This circle calculator finds c (circumference), d (diameter), a (area), and r (radius) of a circle.
There are many circle formulas, such as the area of a circle formula, circumference formula, and diameter formula, all of which are discussed below along with the equations for a circle. Parts of a circle. The figure below shows the key parts of a circle that we need to know to be able to work with circles and their formulas.
Circles are an important geometric shape. The distance around a circle is called the circumference, and the interior space of a circle is called the area. Calculating the circumference and area of a circle requires a number called pi (\(\ \pi\)), which is a non-terminating, non-repeating decimal.
