Answer 1

Answer:

Explanation:

If the radius of the bigger circle is 1, then diameter = 2 units. Which in turn equals to diagonal of square.

Let the side of the square be x. Then x2 + x2 = 22 ⇒ 2x2 = 4 ⇒ x =

Now diameter of the inner circle = side of the square. So radius of the inner circle =

Areas marked by 1, 2, 3, 4 = (Area of the circle - area of the square)/4 =

=

= 0.285

Areas marked by 5, 6, 7, 8 = (Area of the square - area of the inner circle)/4 =

=

= 0.1075

So Area marked by 4 is bigger.
