Question

a wire is in the form of a cricle a radius 42cm it is bent into a square find its sides​

Answer 1

CIRCLE

r= 42cm

length of wire = circumference of circle = 2πr = 2X22X42/7 = 264 cm

perimeter of square = length of wire

4a = 264

a = 66cm

so each side of square = 66cm

Answer 2

Perimeter of the circle=perimeter of the square

2×pi×r=4a

=2×22/7×42

=44×6

=264

264=4a

a=264/4

a=66cm

a=side

Answer=66cm
