Diameter a line segment passing through the centre of a circle and having its endpoints on the circle is called a diameter of the circle.

Diameter a line segment through the centre of a sphere and with the end-points on the sphere is called a diameter of the sphere.

Chord of a circle a line segment with its end- points lying on a circle is called the chord of the circle.

DIAMETER A chord passing through the centre of a circle is known as its diameter. Note that a circle has many diameters and a diameter of a given circle is one of the largest chords of the circle.Also all diameters are of the same length.

Circle : Diameter: : ?

The diameter of a circle is a line which joins two points on the circle and also passes through the centre of the circle. (In the adjoining figure, AB is a diameter of the circle, C is its centre.) Express the diameter of the circle (d) in terms of its radius (r).

Draw a line segment XY as the diameter of a circle .
