Can anyone tell me what i’m doing wrong. it’s not giving me the full marks.

Area shaded part = 116 to three sig digs.

Step-by-step explanation:

I don't know if your answer is correct or not, but the number of sig digs is not. The way the question has been posed is not to 3 sig digs either.

The answer should be 116 if they want it to three sig digs.

Let's see if the answer is correct

Area of the whole circle.

Area of unshaded smaller circle

Area of the shaded part

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
