Help asap!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

Explanation:

`{x}^(2) = 2 * {4}^(2) \\ {x}^(2) = 32 \\ x = 4 √(2) \\ diameter = 4 √(2) \\ radius = 2 √(2) \\ area \: of \: half \: of \: the \: circle = \\`

`a = \frac{\pi * {(2 √(2) )}^(2) }{2} = 4\pi \\ area \: of \: triangle \: = \\ 2 √(2) * 2 √(2) = 8 \\ area \: of \: shaded \: region \: is \: = \\ 4\pi - 8 = 4.57 \: {cm}^(2)`
