Learn about the different parts of a circle, such as radius, diameter, circumference, chord, tangent, secant, arc, segment, and sector. Find formulas and examples to calculate and apply these parts of a circle in geometry.
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.
A circle is a two-dimensional closed figure that has no edges or corners. Learn the definition of circle, different parts of circle, solved examples and more.
3 sie 2023 · Parts of a Circle. 1) Radius – The line that joins the center of the circle to the outer boundary. It is usually represented by ‘ r ’ or ‘ R ’. The plural of radius is called radii. 2) Diameter – The line segment whose endpoints lie on the circle and that passes through the center. Its length is twice the length of a radius.
Learn about the different parts of a circle, such as centre, radius, diameter, circumference, tangent, secant, chord, arc, segment and sector. See diagrams, definitions and examples of each part of a circle and how to draw a circle using a compass.
Radius, Diameter and Circumference. The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle. And here is the really cool thing:
Although there are many parts of a circle, the 8 main parts of a circle include the radius, diameter, circumference, arc, chord, tangent, segment, and sector. What is the Circumference of a Circle? The circumference of a circle is the total length of its boundary.
