Answer:
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
