Question

A wire is in the form of a circle of radius 42 cm. It is bent into a square. Find

the side of the square. ( Take π = 22
7
)

Answer 1

the length of the wire = the perimeter of the circle = 2πx42 = (44x6)cm. the perimeter of the square = the length of the wire = 44x6 cm. Hence the length of the sides of the square = 44x6\4 = 66cm
