Answer 1

9.42 square units

Explanation:

`radius \: (r) = 2 \: units \\ central \: \angle \: ( \theta) = 360 \degree - 90 \degree = 270 \degree \\ \\ area \: of \: shape \\ = ( \theta)/(360 \degree) * \pi {r}^(2) \\ \\ = ( 270 \degree)/(360 \degree) * 3.14 * {2}^(2) \\ \\ = ( 3)/(4) * 3.14 * 4 \\ \\ = 3 * 3.14 \\ \\ = 9.42 \: {units}^(2)`
