Atriangle is inside a circle where the triangle's base is on the circle's diameter as shown.

what is the area of the shaded region?

use 3.14 for π .

enter your answer as a decimal in the box.

Step-by-step explanation:

We will find the shaded area if we subtract the area of the triangle from the area of the circle.

We know that the area of the circle is defined as

Where is half the diameter, that is

The area of the circle is

Now, we have to find the area of the triangle, which is defined as

Where is the base of 16 feet, and is the height of the triangle which is on the radius. So, we have and .

The area of the triangle is

Now, the shaded is the difference as we said before, that is

Replacing both areas, we have

Therefore, the shaded area is
