What is a Yen?
Circles are round shapes with no corners or edges. It consists of all points that are the same distance from the center. The center of the district The center of the circle is the center of the circle. All points in the circle are the same distance from the center.
Radius (r)
The radius is a straight line from the center of the circle to each point in the circle.
Half the diameter length.
All radii (multiple radii) of a circle are the same. radius.
Diameter (d)
Diameter is a straight line that flows through the center of the circle and touches both sides of the circle.
It is the longest line in a circle.
Example:
A very complete pizza pane is diameter from one side through the center.
Scope
The scope is the boundary (outer edge) of a circle. It is the overall distance around the circle.
It’s like a circle range.
Range
The limit of a round garden is its range.
Code
The code is a straight line that connects two points in a circle, but does not pass through the middle.
The longest cord in a circle is the diameter!
Bogen
The curve is the curved part of the circle. It’s like a small section around it.
Small arcs are called small arcs.
The large arc is called the main arch.
Sector
Sectors are part of a circle that looks like pizza panes. It is made up of two radii and an arch.
Small sectors are called small sectors.
Large sectors are called the main sector.
Segments
Segments are part of a circle blocked by chords. Center is not included.
Small segments are called small segments.
Large segments are called main segments. Glass.
Tangente
Tangent is a straight line that touches a circle at just one point. It won’t fit into the circle.
Example:
A bicycle tire that touches the street at some point.
From the center to any point in the circle, the wheel speaks a line passing through the center, with each side cut in two halves.
Round platform circular edge circles (edges) management.
This connects two points in the circle, but not through the center of the bridge. Pizza-like circles slice the cut pieces of cake
Slice of watermelon segmented portions of the circle cut by chords
Terminate a line that touches the circle at one point
Draw and mark a circle
Draw a large circle on paper.

If the circle has a radius of 5 cm, what is the diameter?
(Answer: Diameter = 2 5 = 10 cm)
If the diameter of a circle is 20 cm, what is the radius?
(Answer: radius = 20 raw 2 = 10 cm)
If the circumference of a circular table is 31.4 cm, what is the radius? (Used = 3.14)
(Answer: radius = curionferference・(2) = 31.4Ã・(23.14) = 5 cm)
