Answers
Answer:
Radius refers to the line segment from the center of the circle to an endpoint on the circle. The diameter of a circle is twice the length of the radius, or it can be said that the radius is half the length of the diameter.
Answer:
1.
The chord of a circle which passes through the centre of the circle is called the diameter of the circle. The diameter of a circle is the distance across a circle. The diameter is also the longest chord of a circle. Diameter of a circle d = 2r, where r is the radius of the circle.
2. . A chord of a circle is a line joining two points of the circumference. A chord passes through the centre is called diameter.
3. A segment of a circle is defined as a region bounded by the chord and the corresponding arc lying between the endpoints of the chord. In other words, we can define it as a region of a circle, by breaking the circle through a secant of chord. ... (ii) Minor segment.
4.A sector of a circle is defined as a part of a circle arc, where the end points of the arc are joined to the midpoint of the circle. It is also defined as the part of the circumference(arc) and radii of the circle at the end points of the arc.
