Question

the perimeter of a circle is equal to the perimeter of scared and there area are in the ratio
​

Answer 1

According to the question,

Perimeter of circle = Perimeter of square

∴ 2πr = 4(side)

∴ πr = 2(side)

Squaring both side we get,

π×πr² = 4(side)²

We know that, Area of circle = πr²

& Area of square = (side)²

∴π×(Area of circle) = 4(Area of square)

$∴ \frac{area \: of \: circle}{area \: of \: square} = \frac{4}{\pi}$
