    Exercise 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
    NCERT Solutions for Class 6 Maths Chapter 4 Basic Geometrical Ideas
    (f) a point in the exterior
    (g) a sector
    (h) a segment.
    Solution:
    In the given figure,
    (a) O is the centre of the circle.
    (b) Three radii of the given circle are \(\overline {OA }\) , \(\overline { OB }\) and \(\overline { OC }\) .
    (c) \(\overline { AC }\) is a diameter of the circle.
    (d) \(\overline { ED }\) is a chord of the circle.
    (e) O and P are in the interior of the circle.
    (f) Q is a point in the exterior of the circle.
    (g) OBA is a sector of the circle.
    (h) EDSE, the shaded region is a segment of the circle.

    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, every diameter is the longest chord of a circle.
    (b) No, every chord is not diameter of a circle.

    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:
    In the given circle,
    NCERT Solutions for Class 6 Maths Chapter 4 Basic Geometrical Ideas
    (a) O is the center.
    (b) \(\overline { OA }\) is a radious.
    (c) \(\overline { PQ }\) is a diameter.
    (d) OQC is a sector (shaded part)
    (e) PSR (shaded part) in the segment.
    (f) M is in the interior of the circle.
    (g) K is in the exterior of the circle.
    (h) \(\breve { EF }\) is an arc of the circle.

    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
    (b) True
