Question

if the perimeter of circle is equal to perimeter of square than find the ratio of area of circle to area of square​

Answer 1

Step-by-step explanation:

Perimeter of circle = 2πr

Perimeter of square = 4*side

Given,

2πr = 4*side

πr = 2side

22r/7 = 2side

r = 7/11 side

Area of circle = πr²

Area of square = side²

Ratio = πr² / side²

Ratio = 22/7 × 7/11 side² / side²

( r = 7/11 side)

Ratio = 22/7 × 7/11

Ratio = 2/1

Ratio of areas = 2:1
