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 a circle = pi*r^2r = 6.5 cm  Note: this is 2 sig digs.pi= 3.14Area = 3.14 * 6.5^2Area = 3.14 * 42.25Area= 132.665

Area of unshaded smaller circle

pi = 3.14r = 2.3Area  = 3.14 * 2.3^2Area = 3.14 * 5.29Area = 16.61

Area of the shaded part

Area of shaded part = area of the whole circle - Area of smaller circleArea of the shaded part = 132.66 - 16.61Area of the shaded part = 116.01To 3 sig digs is 116

Ya i could just need to know what type of math

The only number less than 8 that can equal 12 would be 6, 36 is the dividend
