Question

find the area of square which inscribed in a circle whose circle is 8cm​

Answer 1

circle radius = 8cm

then diameter = 16cm

that is the length of the diagnol of a square

if side of square is a then the length of its diagnol = sqrt2 ×a

= 16

a = 16÷sqrt2

area of square = a² = 16²÷ 2 = 128 sqcm
