Please mark me as brainliest and HOPE it HELPS

Step-by-step explanation:

As per the question,

We have been provided that the TWO circles intersect each other such that each CIRCLE PASSES through the CENTRE of the other.

That is,

If the two circle passes through their respective centre, that means two circles have equal radius.

And the distance between their centres is equal to the radius of both circle.

As it is given that distance between their respective centres is 12 cm.

Hence,  the radius of each circle = 12 cm

DENOMINATOR of RATIONAL NUMBER 5/3 is 3

ong>Answer:

To get the CIRCUMFERENCE, simply MULTIPLY the radius by 2π. So, the circumference can be FOUND by multiplying 3 centimeter (1.2 in) by 2π. 3 centimeter (1.2 in) x 2π = 18.84 centimeter (7.4 in). Multiply the circumference of the circle by the HEIGHT of the cylinder.

Given :

• LENGTH of a wire = 440 m
• The wire is moulded in the form of a circle and a square turn by turn.

To find :

• Ratio of the AREA of the circle to that of square

Concept :

The length of wire 440 m will be equal to the circumference of circle and perimeter of square.

So, by using the formula of circumference find the value of RADIUS of the circle and by using the formula of perimeter of square find the side of the square.

Then substitute the values in the formula of the areas and then calculate their ratio.

Formulas to be used :-

→ Formula of Circumference of circle :-

→ Formula to calculate area of circle :-

→ Formula of perimeter of the square :-

→ Formula to calculate area of square :-

Solution :

Circumference of the circle = 440 m

Radius of the circle :-

• Radius of the circle = 70 m

Area of circle :-

• Area of circle = 15400 m²

Perimeter of square = 440 m

Side of the square :-

• Side of the square = 110 m

Area of square :-

• Area of square = 12100 m²

Ratio of the area of the circle to that of square :-

• Ratio of the area of the circle to that of square = 14 : 11

ong>Step-by-step explanation:P>

We know that the distance between the two points (x

1

,y

1

) and (x

2

,y

2

) is

d=

(x

2

−x

1

)

2

+(y

2

−y

1

)

2

Let the given points be A=(a,7) and B=(−3,a) and the third point given is P(2,−1).

We first FIND the distance between P(2,−1) and A=(a,7) as FOLLOWS:

PA=

(x

2

−x

1

)

2

+(y

2

−y

1

)

2

=

(a−2)

2

+(7−(−1))

2

=

(a−2)

2

+(7+1)

2

=

(a−2)

2

+8

2

=

(a−2)

2

+64

Similarly, the distance between P(2,−1) and B=(−3,a) is:

PB=

(x

2

−x

1

)

2

+(y

2

−y

1

)

2

=

(−3−2)

2

+(a−(−1))

2

=

(−5)

2

+(a+1)

2

=

25+(a+1)

2

Since the point P(2,−1) is equidistant from the points A(a,7) and B=(−3,a), THEREFORE, PA=PB that is:

(a−2)

2

+64

=

25+(a+1)

2

⇒(

(a−2)

2

+64

)

2

=(

25+(a+1)

2

)

2

⇒(a−2)

2

+64=25+(a+1)

2

⇒(a−2)

2

−(a+1)

2

=25−64

⇒(a

2

+4−4a)−(a

⇒a

−1−2a=−39

⇒−6a+3=−39

⇒−6a=−39−3

⇒−6a=−42

⇒a=

Hence, a=7.
