Question

PLEASE HELP ME!!I DONT GET IT

Answer 1

72.96
`{in}^(2)`

Explanation:

Radius = 8 in ( Given)

Area of shaded part:

Area of circle - Area of square

`(\pi * {(8)}^(2) ) - ( (16)/( √(2) ) ) ^(2)`

`= (3.14 * 64) - (256)/(2)`

`= 200.96 - 128`
`= 72.96 \: {in}^(2)`

Hope this helps...

Good luck on your assignment

Answer 2

First, find the area of the shaded circle.
8π^2
64π
Then find the area of the square using 45 45 90 relationships.
16
16/2^1/2
16(2^1/2)/2
8(2^1/2)
Now subtract.
64π-8(2^1/2) is you answer.
