Answer 1

Answer:

plz mark me as brainliest‍

Step-by-step explanation:

Part (i)

Let the radius of the circle be r.

The diameter of the circle =2r

According to the question,

=  

2r

r

​  

 

=  

2

1

​  

 

Part (ii)

The length of the rectangle =4 cm

The breadth of the rectangle =3 cm

So, the diagonal of the rectangle will be

=  

3  

2

+4  

2

 

​  

 

=  

25

​  

=5 cm

According to the question,

=  

4

5

​  

 

Part (iii)

The side of the square 4 cm

So, the perimeter of the square will be

=4×side

=4×4=16 cm

And the area of the square will be

=side  

2

 

=4  

2

=16 cm

According to the question,

=  

16

16

​  

=1

Hence, this is the answer.

Answer 2

Answer

1 = side of square/diameter

2= d/2r

by dividing this we can get ratio.
