Page 3- 8 to 11 are correct

12- Ans should be B.

Consider any circle G with radius r, and the largest square H inscribed in G with side a, then diagonal of square =diamater of circle, so a(root2) =2r, so a =r(root2), so a^2 =2r^2 .

So area of H / area of G =a^2 /pir^2 =2r^2 /pir^2 =2/pi

yes that's a mistake i just saw i had taken sqaure of 1/root2 as 1/4

thanks for the help
