pahiroy1221: mera answer to 25.1 aaya hai 
Shreeshu: square area = 4
length of each side is 2
by pythagoras theorem....diagonal length is  \sqrt{8} 
radius =  \sqrt{8} 
area of circle  =  \pi  r^{2} 
25.132

the area of the square = 4 
therefore length of each side is ,
area = side *side
4 = side *side
2*2 = side *side
therefore length of 1 side = 2
diagonal of a square = side * 
√2
= 2 √ 2 
A.T.Q ,
diagonal of square = radius of the circle 
area = 
πr²
area = 22/7 * 2√2 * 2√2
area = 22/7 * 2 * 2 * 2
area = 22/7 * 8
area = 25 .132 
therefore the answer is 25.132 
     i hope that this will help u.....................^_^
