What is radius, diameter, chord, segment etc. pls tell me all parts of a circle with their definations.

They are the common parts of a circle. You can take reference form the given figure.

** CIRCUMFERENCE -** It can be reffered as to be the perimeter or the outline or the border of a circle.

** CENTER -** The centre point of a circle is known as the center of a circle.

**RADIUS -** A line segment joining the center and the circumference of a circle is known as the radius.

**CHORD -** A line segment that joins two different parts of the circumference is known as the chord.

** DIAMETER -** A line segment joining to parts of the circumference, and aslo that passes through the center of the circle is known as the diameter of the circle. It can be considered as the width of the circle. It is essentially a chord.

Hope it helps,
