Question

The perimeter of a circle is equal to that of a square, then the ratio of their areas is?​

Answer 1

Answer:

14/11

Step-by-step explanation:

Given that:-

2πr = 4 ×side

πr = 2× side

πr/2 = side•••••••••(1)

Now,

Ratio of area of circle to square = πr^2/side^2

=> πr^2/side^2= πr^2/(πr/2)^2

= πr^2 × 4/π^2r^2

= 4/π. = 4/22/7

= 4× 7/22

=14/11

● Hence the ratio of area of circle to square is 14:11
