2 pi r=4a. 2*22/7*r=4a. 22/7*r=2a. r=2a*7/22=7/11a. area of circle/area of square. =pi r2/a2. = 22/7*7*11a*7/11*a/a2. =14:11Verified answer
hi friend,
let r be the radius of the circle and a be the side of square
then 2πr=4a
πr=2a
ratio of their areas are πr²/a²=(πr²/π²r²)(4)
=4/π
I hope this will help u ;)
