Circle Exercise 14.1 Solution :
Question no – (1)
Solution :
(a) Radii = OA, OE, OB
(b) Diameter = AB
(c) Chord (s) = CD, AB
(d) A sector = AOE
(e) A segment = CD
(f) Points in the interior = S, Q, R
Question no – (2)
Solution :
(a) Radius = OE
(b) a diameter = AB
(c) a segment = CD
(d) an arc = AC
(e) a sector = BOE
Question no – (3)
Solution :
(a) when op < r
(b) when op > r
(c) op = r
Question no – (4)
Solution :
Question no – (5)
Solution :
(a) The path of all the points that are equidistant from a fixed point on a plane is Circle.
(b) The line segment joining the Centre to any point on the circle is called the radius of the circle.
(c) The line segment joining any two points on a circle and passing through the Centre of the circle is called the diameter of the circle.
(d) The number of diameters in a circle is infinite.
(e) The diameter is twice the length of the radius.
(f) The region bounded by an arc and the chord of a circle is called Segment.
(g) The region bounded by an arc and two radii is called Sector.
(h) All radii of a circle are equal.
(i) If we join any two points of a circle by a line segment, we obtain Chord of the circle.
(j) A radius of a circle is a line segment with one end point on Centre and the other point on circumference.
(k) Two circles are concentric if they have the same Centre and different radii.
Question no – (6)
Solution :
(a) Given Statement is – True
(b) Given Statement is – True
(c) Given Statement is – False
(d) Given Statement is – True
(e) Given Statement is – False
(f) Given Statement is – False
(g) Given Statement is – True
(h) Given Statement is – True
(i) Given Statement is – True
(j) Given Statement is – True
(k) Given Statement is – False
Question no – (7)
Solution :
Question no – (8)
Solution :
(a) Secants = RS, PQ, AB, RQ
(b) Diameters = PQ, CD
(c) Tangent = l
Question no – (9)
Solution :
(a) D = 6 cm
∴ r = 6/2
= 3 cm
(b) D = 12 cm
∴ r = 12/2
= 6 cm
(c) D = 20 cm
=> r = 20/2
= 10 cm
(d) D = 14 cm
=> r = 14/2
= 7 cm
Question no – (10)
Solution :
(a) r = 5.5 cm
∴ D = (2 × 5.5)
= 11.0 cm
(b) r = 3 cm
=> D = (2 × 3) cm
= 6 cm
(c) r = 9 cm
=> D = (2 × 9) cm
= 18 cm
(d) r = 6.5 cm
=> D = (2 × 6.5)
= 13.0 cm
