Answer 1

6.28 square units

Explanation:

`area \: of \: semicircle \\ = (1)/(2) \pi {r}^(2) \\ = (1)/(2) * 3.14 * {2}^(2) \\ = (1)/(2) * 3.14 * 4 \\ = 3.14 * 2 \\ = 6.28 \: {units}^(2)`

Answer 2

Answer:6.284m2

Explanation:

Semi circle is πr^2/2

R=2

Area= 3.142×2×2/2

Area= 12.568/2

Area= 6.284m2
