Question

A wire in the form of a circle of radius 98 cm is cut and bent in the form of a square.The side of the square is

Answer 1

circumference of the circle = perimeter of the square

so 2 × 22/7 × 98 = 4 × side

44×14/4 = side
11×14 = side
154 cm = side

hope this helps you out!

Answer 2

as the circumference of the circle=the perimeter of square
2πr=4×S
2×22/7×98=4S
2×22×14=4S
11×14=S
154=S
Therefore the side of the square is 154cm.
