## NCERT Solutions for Class 6 Maths Chapter 4 Basic Geometrical Ideas Ex 4.6

Question 1.

From the figure, identify:

**(a)** the centre of circle

**(b)** three radii

**(c)** a diameter

**(d)** a chord

**(e)** two points in the interior

**(f)** a point in the exterior

**(g)** a sector

**(h) **a segment

Solution:

**(a)** O is the centre of the circle.

**(b)** OA, OB and OC are three radii of circle.

**(c)** AC is a diameter of circle.

**(d)** ED is a chord of circle.

**(e)** Points O and P are in the interior of circle.

**(f)** Point Q is in the exterior of circle.

**(g)** OAB is a sector of circle.

**(h)** Shaded region in the interior of a circle enclosed by a chord ED.

Question 2.

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

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

Solution:

**(a)** Yes, a diameter is the longest chord.

**(b)** Not always.

Question 3.

Draw any circle and mark

**(a)** its centre

**(b)** a radius

**(c)** a diameter

**(d)** a Sector

**(e)** a segment

**(f)** a point in its interior

**(g)** a point in its exterior

**(h)** an arc

Solution:

Draw any circle and its various parts are as under :

**(a)** Its centre is O.

**(b)** Its radii are OA, OB and OC.

**(c)** Its diameter is AOC.

**(d)** Its sector is OAB.

**(e)** Shaded region in the interior of a circle enclosed by a chord PQ.

**(f)** M is a point in its interior.

**(g)** N is a point in its exterior.

**(h)** BC is an arc.

Question 4.

Say true or false:

**(a)** Two diameters of a circle will necessarily intersect.

**(b)** The centre of a circle is always in its interior.

Solution:

**(a)** True, because each diameter passes through the centre of a circle.

**(b)** True.
