A circle of radius 7 m is cut to form a square. The length of the side of the square formed =
The correct option is A 11 m
Since a circle is cut to form a square, so, the circumference of the circle will be equal to the perimeter of the square formed.
The circumference of a circle = 2πr = 2×227×7 = 44 m.
Also, the perimeter of a square = 4×side ,
⇒ 4×side = 44 m,
⇒ side length = 11 m.
