Question

the area of a square is same as the area of a circle . the ratio of their parameters is

Answer 1

Hola!

Let the radius of circle be = r
n'
Let the side of the square be = a

Given, πr² = a² = a = r √π

ATQ,
Ratio of their perimeters = $\frac{2πr}{4a}$

= $\frac{πr}{2a}$

= $\frac{πr}{2r √π}$

= √π / 2

Hence,
Ratio of their perimeters is √π : 2

Hope it helps! :D
