Question

The perimeter of square and circle are equal. R is radius of circle and S is side of square then area of circle in terms of S is​

Answer 1

Answer:

area of circle=πr² (radius r)

area of square=a² (side a)

πr²=a²

r=a/√π

circumference of circle/perimeter of square

=2πr/4a

=(2πa/√π)/4a

=2πa/√π4a

=√π/2

Answer 2

Answer:

$area \: of \: a \: circle \: = \pi \: r {}^{2}$

$area \: of \: a \: square \: = \: s \: {}^{2}$

$\pi \: r \: {}^{2} = s {}^{2}$

$= r = \frac{s}{ \sqrt{\pi} }$

$cirumferenc \: = 2\pi \: r( \frac{s}{ \sqrt{\pi} } )$

$= (2s) \sqrt{\pi}$
