Question

Four circle inscribed in a square area of shaded region

Answer 1

Hey dear,
Down here,
-----------------------------------------------------
Let the side of the square be 'a'.
Therefore, radius of each circle = a/4.
Thus the area of shaded region = Area of square - Area of Four circles
= a^2 - π(a/4)^2
= a^2{1 - π/8}...
