Answer 2

Answer:

9.42 square units

Step-by-step explanation:

$central \: \angle \: ( \theta) = 90 \degree \\ radius \: (r) = 2 \: units \\ Area \: of \: sector = \frac{ \theta}{360 \degree} \times \pi {r}^{2} \\ \\ = \frac{ 90 \degree}{360 \degree} \times \pi \times {2}^{2} \\ \\ = \frac{ 1}{4} \times \pi\times 4 \\ \\ =\pi \: {units}^{2}$

Area of shape = Area of circle - Area of sector

$= \pi r^2 - \pi\\=\pi(r^2 -1)\\=3.14(2^2 -1)\\=3.14(4 -1)\\=3.14\times 3\\= 9.42\: units^2$
