Question

A circle of radius 7 m is cut to form a square. The length of the side of the square formed =

A
11 m
B
14 m
C
7 m
D
22 m

Solution

The correct option is A 11 mSince 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.
