Question

what is the ratio of the perimeter of the squre to the circle when the length of diameter of the circle is equal to the side length of the square?​

Answer 1

Answer:

Ratio is 14:11

Step-by-step explanation:

given

d=s(d is diameter and s is side of the square)

d=2r(r is radius)

2r=s

perimeter of square=4s=4(2r)=8r

perimeter of circle=2πr=2 x 22/7 x r=44/7r

ratio = 8r/44r/7=8r x 7/44r =56r/44r=14/11

therefore ratio is 14:11

Answer 2

Answer:

4 : π

Step-by-step explanation:

Given -

Diameter = Side

Find -

Perimeter(square) : Perimeter(circle)

Solution -

$Perimeter(square) / Perimeter(circle)\\= 4side / 2\pi r\\= 4d / 2\pi r...[Given]\\=4d/\pi d....[2r = d]\\= 4 / \pi$

Hence, Perimeter(square) : Perimeter(Circle) = 4 : π
