Explain the following: Circle          (ii)   Radius      (iii)   Centre Diameter     (v)  Chord        (v)  Interior of a circle

In given figure, O is the centre of the circle. A chord, which is not the diameter of the circle is

In the given figure, O is the centre of the circle. Name a chord, which is not the diameter of the circle.

The equation of the circle whose diameter is common chord to the circles

In Fig. 2.47, O is the centre of the circle. Name a chord, which is not the diameter of the circle.

(a) Is every diameter of a circle also a chord? (b) Is every chord of a circle also a diameter?

Prove that the diameter is the greatest chord in a circle.

Write True or False: Give reasons for your answers. (i) Line segment joining the centre to any point on the circle is a radius of the circle. (ii) A circle has only finite number of equal chords. (iii) If a circle is divided into three equal arcs, each is a major arc. (iv) A chord of a circle, which is twice as long as its radius, is a diameter of the circle. (v) Sector is the region between the chord and its corresponding arc. (vi) A circle is a plane figure.

A chord of length 16 cm is drawn in a circle of radius 10 cm .Calculate the distance of the chord from the centre of the circle.

Is every chord of a circle also a diameter?
