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

Ex 4.6 Class 6 Maths 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.

Ex 4.6 Class 6 Maths 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.

Ex 4.6 Class 6 Maths 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.

Ex 4.6 Class 6 Maths 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.
