Question

A circle is inscribed in a square whose each side is 36 CM. find the area of the circular region.

Answer 1

Let square be ABCD
And circle with centre O
Hence
AB²+BC²=AC²
AC is diameter
36²+36²=AC²
1296+1296=AC²
2592=AC²
50.91=AC
25.45=AO
$\pi r^{2} = area$
22/7*25.45*25.45 = area
2035.6 = area
Hope it helps....
