Write a couple sentences to explain how you would find the area of the shaded region:

Answer:
I would find the area of the circle and then find the area of the shape in the middle and then minus that from the area of the whole circle
Answer:
Step-by-step explanation:
1. Find the area of the circle. Area_c = pi * r^2
2.Find the area of the pentagon in terms of the radius Area_P =
3 sqrt(3) r^2 / 2
The answer you want is Area_shade = Area_c - area_P
Area = pi * r^2 - 3 sqrt(3)r^2/2
Area = r^2 (pi - 3 sqrt(3)/2)
