Question

Find area of shaded region

Answer 1

21. 99

Explanation:

`s = \pi * {r}^(2) \\ s1 = 3.14 * 9 = 28.27 \\ s2 = 3.14 * 1 = 3.14 \\ a = 28.27 - (3.14 * 2) = 28.27 - 6.28 = 21.99`

Answer 2

The answer is 21.98. I just took area of the whole circle and subtracted it with the area of two circles in it
