Question

The perimeter of a square and the circumference of a circle are equal. If the radius of the circle is r and side of the square is S, then the area of the circle in terms of S is _____.

Answer 1

Answer:

hope it helps you .....

Step-by-step explanation:

area of circle will be= S²

Answer 2

Answer:

4s^2/π

perimeter of square with side s is 4s,

circumference of circle is 2πr,

given that they both are equal,

4s=2πr,

r=2s/π.

then area of circle is πr^2=π(2s/π)^2=4s^2/π
