Question : 20 of 40

Marks: +1, -0

If the circumference of a circle is equal to the perimeter of a square, then their areas are in the ratio of

Solution:

Here, 2πR = 4x ⇒ R =

{2x}/π

∴ Ratio between the areas of the circle and the square =

πR^2 : x^2

π× ({2x}/p)^2 : x^2

{4x^2}/π : x^2

4 : {22]/7

= 14 : 11
