Question

if perimeter of the circle is equal to that of the square,then the ratio of their areas is​

Answer 1

Step-by-step explanation:

Let the radius of a circle = r

the circumference = 2pir& area pi r2

if the given that circumference of circle is same as perimeter of square

square on side = 1 upon 4× circumference of given circle

= 1upon 4×2pi r =pi r upon 2

area of square =(pi r upon 2)2

so area of circle: area of square

= pi r2:(pi r 2 upon2 =4upon pi =4upon 2upon 7 =14upon 11
