ANSWER

If a line is drawn parallel to one side of a triangle to intersect the

other two sides in distinct points, the other two sides are divided in the same ratio.

As PQ∥BC

So

PB

AP

=

QC

AQ

∠AQP=∠ACB

∠APQ=∠ABC

So by AAA △AQP∼△ACB

The ratio of the areas of two similar triangles is equal to the square of the ratio of their corresponding sides.

Hence

Area(ABC)

Area(APQ)

=

(AB)

(AP)

Area(ABC)

Area(APQ)

Let Area(APQ)=k

Area(ABC)=9k

Area(BPQC)=Area(ABC)−Area(APQ)=9k−k=8k

Area(BPQC)

Area(APQ)

13.	The sum of the first n terms of an AP is (3n2+6n) find the nth term and the 15 of an AP
Answer» Step-by-step EXPLANATION: Let the sum of first n TERMS of the A.P.=Sn Given: Sn = 3n2 – 4N ...(i) Now, Replacing n by (n –1) in (i), we get, Sn – 1 = 3(n – 1)2 – 4(n – 1) nth term of the A.P. an = Sn – Sn – 1 ∴ an = (3n2 – 4n) – [3(n – 1)2 – 4(n – 1)] ⇒ an = 3 [ n2 – (n – 1)2] – 4 [n – (n – 1)] ⇒ an = 3 (n2 – n2 + 2n – 1) – 4 (n – n + 1) ⇒ an = 3(2n –1) – 4 ⇒ an = 6n – 3 – 4 ⇒ an= 6n – 7 Thus, the nth term of the A.P = 6n – 7.

13.

The sum of the first n terms of an AP is (3n2+6n) find the nth term and the 15 of an AP

Answer»

Step-by-step EXPLANATION:

Let the sum of first n TERMS of the A.P.=Sn

Given: Sn = 3n2 – 4N ...(i)

Now,

Replacing n by (n –1) in (i), we get,

Sn – 1 = 3(n – 1)2 – 4(n – 1)

nth term of the A.P. an = Sn – Sn – 1

∴ an = (3n2 – 4n) – [3(n – 1)2 – 4(n – 1)]

⇒ an = 3 [ n2 – (n – 1)2] – 4 [n – (n – 1)]

⇒ an = 3 (n2 – n2 + 2n – 1) – 4 (n – n + 1)

⇒ an = 3(2n –1) – 4

⇒ an = 6n – 3 – 4

⇒ an= 6n – 7

Thus, the nth term of the A.P = 6n – 7.

15.	18. The difference between outside and inside radii of a metallic cylindrical pipe of length 14 cm is 2 CM if the pipe is made of metal, find the outer and inner radii of the pipe
Answer» r= inner radius R= outer radius h= height of the metallic pipe = 14 cm Difference between the CURVED surface area of the outer CYLINDER and Curved surface area of the inner cylinder = 2πRh - 2πrh. Given: difference between the outside and inside curved surface area of cylinder=44 cm2 . so, 2πh( R - r) = 44 2 x 22/ 7 x 14 ( R - r) = 44 R - r = 1 / 2 = 0.5 Given: the pipe is made up of METAL= 99 cm³ Volume of cylindrical metallic pipe = πR²h - πr²h. so, 22/7 x 14 (R² - r²) = 99 44(R² - r²) = 99 (R² - r²) = 9 / 4 R²-r²= 2.25 ( R - r)(R + r) = 2.25 (0.5)(R + r) = 2.25 R + r = 2.25 / 0.5 R + r = 4.5 Adding up both the values we get 2R = 4.5 + 0.5 = 5 R = 2.5 cm and r = 2 cm

18. The difference between outside and inside radii of a metallic cylindrical pipe of length 14 cm is 2 CM if the pipe is made of metal, find the outer and inner radii of the pipe

Answer»

r= inner radius

R= outer radius

h= height of the metallic pipe = 14 cm

Difference between the CURVED surface area of the outer CYLINDER and Curved surface area of the inner cylinder = 2πRh - 2πrh.

Given:

difference between the outside and inside curved surface area of cylinder=44 cm2 .

so,

2πh( R - r) = 44

2 x 22/ 7 x 14 ( R - r) = 44

R - r = 1 / 2

= 0.5

Given:

the pipe is made up of METAL= 99 cm³

Volume of cylindrical metallic pipe = πR²h - πr²h.

so,

22/7 x 14 (R² - r²) = 99

44(R² - r²) = 99

(R² - r²) = 9 / 4

R²-r²= 2.25

( R - r)(R + r) = 2.25

(0.5)(R + r) = 2.25

R + r = 2.25 / 0.5

R + r = 4.5

Adding up both the values we get

2R = 4.5 + 0.5 = 5

R = 2.5 cm and r = 2 cm
