Find the area of the shaped region
1 answer:
Answer:
Assuming π is represented by 3.14, the correct answer is .
Step-by-step explanation:
Because the question is asking for the area of the shaded region, you can ignore the non-shaded versions of the diagram. The formula of finding the area of a circle is , where r is the radius of the circle. Since the radius of the shaded circle is
, you can infer that the area of the shaded region would be
=
=
