Question

Help? Its high school geometry and I can't figure it out.

Answer 1

The area is about 2.58 in².

Explanation:

First, you have to find the area of the circle inside the square which is about 28.27 in² = πr² (The radius is half of 6 because 6 is the diameter = 3)

Next, you subtract 28.27 from 36, which equals to 7.73.

Finally, you divide 7.73 by 2 because there are 2 shapes of the same size. You get about 3.865.

So, I would say : Area of the yellow region ≈ 3.865 in²

Answer 2

The area of the square is 6 x 6 = 36 square inches.

There are two semi circles which would make a complete circle.

Area of a circle is PI x r^2

The diameter of the circle is the length of the side of the square, the radius is half of that, so r = 3

Area of the circle is 3.14 x 3^2 = 3.14 x 9 = 28.26 square inches.

The space in the square not taken up by the circle would be 36 - 28.26 = 7.74 square inches.

The shaded portion is half of that:

Shaded portion = 7.74 / 2 = 3.9 square inches.
