Question

the perimeter of circle equal to dash square that the ratio of areas​

Answer 1

Answer:

πr^2 : a^2

Step-by-step explanation:

Solution :

Let the radius of the circle be r

and side of the square be 'a'.

Then, according to question, 2πr = 4a=> 2πr/4= πr/2

Now, ratio of their areas,

πr^2/(πr2)^2

=πr^2×4/π^2*r^2

= 14/11

= πr^2 : a^2

= 14:11
