11.	in the figure O is the center of the circle and OP⊥AB. If AB =8cm and OP=3cm find the diameter of the circle.
Answer» Given :- OP⊥AB AB = 8CM. OP = 3cm. To Find :- Diameter of circle ? Concept USED :- If a line is drawn from the centre of a circle to the chord , the the line will bisect the chord at right Angle . Pythagoras Theoram . Construction :- JOIN OA . Solution :- in Right ∆OAP , we have :- → OP = 3cm. → AP = (AB/2) = (8/2) = 4cm. So , By Pythagoras Theoram , → AO = √[(3)² + (4)²] → AO = √[9 + 16] → AO = √25 → AO = 5cm. = Radius of circle. So, → Diameter of circle = 2 * Radius = 2 * 5 = 10cm. (Ans). Hence , Diameter of Given Circle is 10cm.

11.

in the figure O is the center of the circle and OP⊥AB. If AB =8cm and OP=3cm find the diameter of the circle.

Answer»

Given :-

OP⊥AB
AB = 8CM.
OP = 3cm.

To Find :-

Diameter of circle ?

Concept USED :-

If a line is drawn from the centre of a circle to the chord , the the line will bisect the chord at right Angle .
Pythagoras Theoram .

Construction :-

JOIN OA .

Solution :-

in Right ∆OAP , we have :-

→ OP = 3cm.

→ AP = (AB/2) = (8/2) = 4cm.

So , By Pythagoras Theoram ,

→ AO = √[(3)² + (4)²]

→ AO = √[9 + 16]

→ AO = √25

→ AO = 5cm. = Radius of circle.

So,

→ Diameter of circle = 2 * Radius = 2 * 5 = 10cm. (Ans).

Hence , Diameter of Given Circle is 10cm.

13.	10. The perimeters of a square and a rectangle are equal. The length of the rectangle is twice the breadth, the side of square is 15 cm, then the area of the rectangle in sq. cm is....*
Answer» SIDE of the square (S) = 15 cm. Perimeter of the square = 4 X S = 4 X 15 = 60 cm. Since it is given that, Perimeter of the square = perimeter of the rectangle so , perimeter of the Rectangle = 60 cm Let the breadth be " X " LENGTH is TWICE the breadth = 2X According to problem 2 ( L + b) = 60 cm 2 ( 2X + X ) = 60 2 (3X) = 60 3X = 60/2 3X = 30 ==> X = 30/3 X = 10 Therefore, Breadth = X =10 cm Length = 2X = 2 (10) = 20cm Area of the rectangle = L X B = 20 cm x 10 cm = 200 cm^2

10. The perimeters of a square and a rectangle are equal. The length of the rectangle is twice the breadth, the side of square is 15 cm, then the area of the rectangle in sq. cm is....*

Answer»

SIDE of the square (S) = 15 cm.

Perimeter of the square = 4 X S

= 4 X 15

= 60 cm.

Since it is given that,

Perimeter of the square = perimeter of the rectangle

so ,

perimeter of the Rectangle = 60 cm

Let the breadth be " X "

LENGTH is TWICE the breadth = 2X

According to problem

2 ( L + b) = 60 cm

2 ( 2X + X ) = 60

2 (3X) = 60

3X = 60/2

3X = 30

==> X = 30/3

X = 10

Therefore,

Breadth = X =10 cm

Length = 2X = 2 (10) = 20cm

Area of the rectangle = L X B

= 20 cm x 10 cm

= 200 cm^2

39.	< 8000.20.The ratio between the preset ages of A and B is 4:3. IfB's present age is 21 years, what will be the ratioof their ages 4 years hence ?1
Answer» Given : The ratio between the preset AGES of A and B is 4:3. B's present age is 21 YEARS. To find : The ratio of their ages 4 years hence =? Step-by-step explanation: Let, the ratio of the present age of B's = 3x. We know that, B's present age = 21 years [Given] According to the question : ➟ 3x = 21 ➟ x = 21/3 ➟ x = 7 So, We will know that the VALUE of x = 7. Now, Let, the ratio of the A's present age = 4x. We know that the value of x = 7 So, 4x = 4 × 7 = 28 Thus, The A's present age = 28 years. Now, A's age will be 4 years from hence = 28 + 4 = 32 years Then, B's age will be 4 years from hence = 21 + 4 = 25 years The ratio of their ages 4 years hence = A's age : B's age. Substituting the values, we get 32 : 25 Thus, The ratio of their ages will be 4 years hence = 32 : 25

< 8000.20.The ratio between the preset ages of A and B is 4:3. IfB's present age is 21 years, what will be the ratioof their ages 4 years hence ?1

Answer»

Given :

The ratio between the preset AGES of A and B is 4:3.

B's present age is 21 YEARS.

To find :

The ratio of their ages 4 years hence =?

Step-by-step explanation:

Let, the ratio of the present age of B's = 3x.

We know that,

B's present age = 21 years [Given]

According to the question :

➟ 3x = 21

➟ x = 21/3

➟ x = 7

So, We will know that the VALUE of x = 7.

Now,

Let, the ratio of the A's present age = 4x.

We know that the value of x = 7

So, 4x

= 4 × 7

= 28

Thus, The A's present age = 28 years.

Now,

A's age will be 4 years from hence = 28 + 4 = 32 years

Then, B's age will be 4 years from hence = 21 + 4 = 25 years

The ratio of their ages 4 years hence = A's age : B's age.

Substituting the values, we get

32 : 25

Thus, The ratio of their ages will be 4 years hence = 32 : 25
