First, let's find the area of the circle. We see that the radius is 4. Plug that into the area of a circle equation, and you get 16pi. Now, we need to find the area of the triangle. To do this, we see that QO=OP, and therefore OP=4. So, we use the area of a triangle equation, and we get that the area is 8. Subtract that from 16pi, and the answer is 16pi-8.
