Question

if a circle is of 42 CM radius and it is bent into a square so what is the side of square

Answer 1

radius of circle =42cm
circumference=2*22/7*42
263.76cm
side of square
perimeter of square =4s
4s=263.76
s=263.76/4
=65.94cm

Answer 2

given : radius of circle =42cm
to find : side of a square
solution : perimeter of circle and square are equal of same length
so circumference of a circle=perimeter of a square
2πr=4×side
2×22/7×42=4×side
264=4×side
264/4=side
66cm^2=side of a square
