Case Based Questions Test: Circles - Question 1

### Read the following text and answer the following question on the basis of the same:A farmer has a field in the shape of triangle with AB = 13 cm, BC = 14 cm and AE = 7 cm. He wants to leave a space in the form of a circular field for growing wheat and the remaining for growing vegetables. Q. The measure of BF is:

Detailed Solution for Case Based Questions Test: Circles - Question 1

∴ AB = 13 cm (given)

∴ BF = AB – AF

= (13 – 7) cm

AE = 7 cm (given)

Then, AF = AE (Tangents of the circle)

⇒ AF = 7 cm.

[Proved, AF = 7 cm]

BF = 6 cm

Case Based Questions Test: Circles - Question 2

### Read the following text and answer the following question on the basis of the same:A farmer has a field in the shape of triangle with AB = 13 cm, BC = 14 cm and AE = 7 cm. He wants to leave a space in the form of a circular field for growing wheat and the remaining for growing vegetables. Q. The measure of CE + CD is:

Detailed Solution for Case Based Questions Test: Circles - Question 2

∴ AB = 13 cm (given)

∴ BF = AB – AF

BC = 14 cm (given)

= (13 – 7) cm

AE = 7 cm (given)

Then, AF = AE (Tangents of the circle)

⇒ AF = 7 cm.

[Proved, AF = 7 cm]

BF = 6 cm

BF = 6 cm (Proved)

∴ BD = BF (Tangents of the circle)

So, BD = 6 cm.

and BD = 6 cm [Proved]

then CD = BC – BD

= (14 – 6) cm = 8 cm

but CD = CE (Tangents of the circle)

∴ CE = 8 cm

So, CD + CE = (8 + 8) cm = 16 cm.

Case Based Questions Test: Circles - Question 3

### Read the following text and answer the following question on the basis of the same:A farmer has a field in the shape of triangle with AB = 13 cm, BC = 14 cm and AE = 7 cm. He wants to leave a space in the form of a circular field for growing wheat and the remaining for growing vegetables. Q. The measure of AF is:

Detailed Solution for Case Based Questions Test: Circles - Question 3 AE = 7 cm (given)

Then, AF = AE (Tangents of the circle)

⇒ AF = 7 cm.

Case Based Questions Test: Circles - Question 4

Read the following text and answer the following question on the basis of the same:

A farmer has a field in the shape of triangle with AB = 13 cm, BC = 14 cm and AE = 7 cm. He wants to leave a space in the form of a circular field for growing wheat and the remaining for growing vegetables. Q. The measure of BD is:

Detailed Solution for Case Based Questions Test: Circles - Question 4

∴ AB = 13 cm (given)

BF = AB – AF

= (13 – 7) cm

[Proved in Q. 1., AF = 7 cm]

BF = 6 cm

BF = 6 cm (Proved)

∴ BD = BF (Tangents of the circle)

So, BD = 6 cm.

Case Based Questions Test: Circles - Question 5

Read the following text and answer the following question on the basis of the same:

A farmer has a field in the shape of triangle with AB = 13 cm, BC = 14 cm and AE = 7 cm. He wants to leave a space in the form of a circular field for growing wheat and the remaining for growing vegetables. Q. The measure of AC is:

Detailed Solution for Case Based Questions Test: Circles - Question 5

∴ AB = 13 cm (given)

BF = AB – AF

= (13 – 7) cm

AE = 7 cm (given)

Then, AF = AE (Tangents of the circle)

⇒ AF = 7 cm.

[Proved AF = 7 cm]

BF = 6 cm

BC = 14 cm (given)

and BD = 6 cm [Proved in Q. 3]

then CD = BC – BD

= (14 – 6) cm = 8 cm

but CD = CE (Tangents of the circle)

∴ CE = 8 cm

So, CD + CE = (8 + 8) cm = 16 cm.

CE = 8 cm

and AE = 7 cm (given)

then, AC = AE + EC

= (7 + 8) cm

= 15 cm.

Case Based Questions Test: Circles - Question 6

Both Assertion and Reason are true but Reason is not correct explanation of Assertion

In the following figure, a circle with centre O is inscribed in a quadrilateral ABCD such that, it touches the sides BC, AB, AD and CD at points P, Q, R and S respectively. If AB = 29 cm, AD = 23 cm, ∠B = 90° and DS = 5 cm. Q. Find the value of AR:

Detailed Solution for Case Based Questions Test: Circles - Question 6

Here, AD = 23 cm (given)

and

Here, DS = 5 cm

but DR = DS (Length of tangents are equal)

then DR = 5 cm.

DR = 5 cm (Proved)

then AR = AD – DR cm

= (23 – 5) cm = 18 cm.

Case Based Questions Test: Circles - Question 7

Both Assertion and Reason are true but Reason is not correct explanation of Assertion

In the following figure, a circle with centre O is inscribed in a quadrilateral ABCD such that, it touches the sides BC, AB, AD and CD at points P, Q, R and S respectively. If AB = 29 cm, AD = 23 cm, ∠B = 90° and DS = 5 cm. Q. Find the value of BP:

Detailed Solution for Case Based Questions Test: Circles - Question 7

AB = 29 cm (given) but AQ = AR(Length of tangents are equal) then AQ = 18 cm

Here, AD = 23 cm (given)

and

Here, DS = 5 cm

but DR = DS (Length of tangents are equal)

then DR = 5 cm.

DR = 5 cm (Proved)

then AR = AD – DR cm

= (23 – 5) cm = 18 cm. [Proved]

∴ BQ = AB – AQ

= (29 – 18) cm = 11 cm.

BQ = 11 cm [Proved]

and BP = BQ (Length of tangents are equal)

∴ BP = 11 cm.

Case Based Questions Test: Circles - Question 8

Both Assertion and Reason are true but Reason is not correct explanation of Assertion

In the following figure, a circle with centre O is inscribed in a quadrilateral ABCD such that, it touches the sides BC, AB, AD and CD at points P, Q, R and S respectively. If AB = 29 cm, AD = 23 cm, ∠B = 90° and DS = 5 cm. Q. Find the value of DR:

Detailed Solution for Case Based Questions Test: Circles - Question 8 Here, DS = 5 cm

but DR = DS

(Length of tangents are equal)

then DR = 5 cm.

Case Based Questions Test: Circles - Question 9

Both Assertion and Reason are true but Reason is not correct explanation of Assertion

In the following figure, a circle with centre O is inscribed in a quadrilateral ABCD such that, it touches the sides BC, AB, AD and CD at points P, Q, R and S respectively. If AB = 29 cm, AD = 23 cm, ∠B = 90° and DS = 5 cm. Q. Find the value of QB:

Detailed Solution for Case Based Questions Test: Circles - Question 9

AB = 29 cm (given)

but AQ = AR (Length of tangents are equal)

then AQ = 18 cm

Here, AD = 23 cm (given)

and

Here, DS = 5 cm

but DR = DS (Length of tangents are equal)

then DR = 5 cm.

DR = 5 cm (Proved)

then AR = AD – DR cm

= (23 – 5) cm = 18 cm. [Proved]

∴ BQ = AB – AQ

= (29 – 18) cm = 11 cm.

Case Based Questions Test: Circles - Question 10
