Me ( show work! ) the directions are to find the shaded region using 3.14.

You have a square with side length 30.
So the area of the square will be 30*30 = 900.

Notice that the right side (with length 30 as well) is actually the length of the diameter of this semi circle.

We know that area of a circle is given by . So then the area of a semi circle is half of that: .

If the diameter of the semi circle is 30,
then the radius is 15.

We'll plug in the radial value of 15, and 3.14 for a good pi approximation and calculate the area of the semi circle: 

The area of the shaded region will be the area of the entire square minus the area of the semi circle: 

The answer mai bc
