the question is in the picture.

The answer is 816 yd^2

To find this we first have to find the area of the overall circle. Then subtract the area of the shaded region from the overall.

The formula to find the area with the diameter is A=1/4 3.1416 d^2.

So first let’s find the area of the overall circle using the formula. A= 1/4 3.1416 36^2= 1,017.88

Now let’s find the area of the shaded region. A= 1/4 3.1416 16^2= 201.06

Now we subtract...

1,017.88
- 201.06


816

So the area of the shaded region is 816 yd^2
