Important Terms Related to Circle
Diameter
The diameter can be termed as a line which is drawn across a circle passing through the center.
Radius
The distance from the middle or center of a circle towards any point on it is a radius. Interestingly, when you place two radii back-to-back, the resultant would hold the same length as one diameter. Therefore, we can call one diameter twice as long as the concerned radius.
Circle Area
In a circle, the area can be stated as π times the square of the radius. It is written as: A = π r2. Taking into consideration the Diameter: A = (π/4) × D2
Chord
A line segment that joins two points present on a curve is called as the chord. In geometry, the usefulness of a chord is focused on describing a line segment connecting two endpoints which rest on a circle.
