Question

what will be reduced form of the ratio of radius to circle to is circumference?​

Answer 1

Answer:

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.
