Answer 2

So now find area of square- area of circle

Answer 3

i got 2r^2 - Pir^2 but the book says 4r^2 - Pir^2

Answer 4

\[4r ^{2} - \pi r^2\]

Answer 5

square has side \(2r\) and so area is \(4r^2\) circle has radius \(r\) and area \(\pi r^2\) subtract and get
\[4r^2-\pi r^2\]

Answer 6

you forgot to square the two

Answer 7

\[4r^2\] You forgot to square your 2 for are of square

Answer 8

\[(2r)^2=4r^2\]

Answer 9

so one side of the square is 2r and the formla would be (2r)^2

Answer 10

Yes

Answer 11

Thanks guys
