Question

Anyone know how to solve this question? Help me friends.

Answer 1

The answer is Option (B)

Given that perimeter of a circle = Perimeter of a square.

$= > 2\pi r = 4s$

$= > \frac{2\pi r}{4} = s$

$= > \frac{\pi r}{2} = s$

Now,

Ratio of their areas :

$= > \frac{\pi r^2}{s^2}$

$= > \frac{\pi r^2}{(\frac{\pi r}{2})^2}$

$= > \frac{\pi r^2}{\frac{\pi^2r^2}{4}}$

$= > \frac{\pi r^2 * 4}{\pi^2 r^2}$

$= > \frac{4}{\pi}$

$= > \frac{4}{\frac{22}{7}}$

$= > \frac{28}{22}$

$= > \frac{14}{11}$

Hope this helps!
