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 = = .
There are 16 smaller triangles within the main large one. .25=1/4, so your fraction is 1/4. 1/4 of 16 is 4, because 4+4+4+4=16. So colour in 4 triangles. Hope this helps!
