Class 10 Mathematics Chapter 10 Circles Worksheet with Answers

 

Circles

Q.- If O is the centre of a circle, PQ is a chord and tangent PR at P makes an angle of with PQ, then POQ is equal to 
WT_circles test 9
a. 110°
b. 120°
c. 100°
d. 90°
 
Ans- b. 120°
Explanation: Here RPO = 90°
∠RPQ = 60° (given)
∴ ∠OPQ = 90° - 60° = 30° PQO = 30° Also [Opposite angles of equal radii] Now,
In triangle OPQ,
∠OPQ +∠ PQO + ∠QOP =180°
=> 30° + 30° + QOP = 180°
=> ∠QOP = 120°
 
Q.- In the given figure, if OQ = 3 cm, OP = 5 m, then the length of PR is 
WT_circles test 10
a. 4 cm
b. 3 cm
c. 5 cm
d. 6 cm
 
Ans- a. 4 cm
Explanation: Here Q = 90° [Angle between tangent and radius through the point of contact]
Now, in right angled triangle OPQ,
OP2 = OQ2 + PQ2
(5)2 = (3)2 + PQ2
PQ2 = 25 - 9 = 16
PQ = 4 cm
But PQ = PR [Tangents from one point to a circle are equal]
Therefore, PR = 4 cm
 
Q.-  In figure, PA and PB are two tangents drawn from an external point P to a circle with centre C and radius 4 cm. If PA ⊥ PB, then the length of each tangent is: 
WT_circles test 11
a. 5 cm
b. 3 cm
c. 4 cm
d. 8 cm
 
Ans- c. 4 cm
WT_circles test 12
Explanation:
Construction: Joined AC and BC. Here CA⊥AP and CB ⊥ BP and PA ⊥ PB Also
AP = PB
Therefore, BPAC is a square. AP = PB = BC = 4 cm
 
Q.- The length of tangent PQ, from an external point Q is 24 cm. If the distance of the point Q from the centre is 25 cm, then the diameter of the circle is 
WT_circles test 14
a. 15 cm
b. 14 cm
c. 12 cm
d. 7 cm
 
Ans- 5. b. 14 cm
WT_circles test 13
Explanation:
Here ∠ OPQ = 90o [Angle between tangent and radius through the point of contact]
OQ2 = OP2 + PQ2 (25)2 = OP2 + (24)2
OP2 = 625 - 576 OP2 = 49
OP2 = 49 OP = 7 cm
Therefore, the diameter = 2 OP = 2 7 = 14 cm
 
Q.- What term will you use for a line which intersect a circle at two distinct points? 

Ans-  A line that interests a circle at two points in a circle is called a Secant.

Q.-In the fig. there are two concentric circles with centre O. PRT and PQS are tangents to the inner circle from a point P lying on the outer circle. If PR = 5 cm find the length of PS. (1)
Ans- PQ = PR = 5 cm ( Length of Tangents from same external point are always equal) and PQ = QS (perpendicular from center of the circle to the chord bisects the chord)
 PS = 2PQ
= 2×5 =10cm
 
Q.-  Find the distance between two parallel tangents of a circle of radius 3 cm.
WT_circles test 15
Ans-  Distance between two parallel tangents = diameter = PQ
PQ = OP + OQ = 3 + 3 = 6cm
The total distance between two parallel tangents lines is 6 cm.
