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

Answer 1

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 = 2$\pi$r = 2$\times$$\frac{22}{7}$$\times$7 = 44 m.
Also, the perimeter of a square = 4$\times$side ,
$\Rightarrow$ 4$\times$side = 44 m,
$\Rightarrow$ side length = 11 m.
