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

Hi there,

area of square =4
so by Pythagoras theorem the diagonal =√8=radius
area of the circle=πr^2=25.132
i hope this helps u...

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
