Question

A wire in the form of circle of diameter 42 cm is cut and bent to form a square. The side of the square is

• A. 16 cm
• B. 17 cm
• C. 33 cm
• D. 16.5 cm

Answer 1

The correct option is C 33 cm

Perimeter of square = Circumference of circle

$4\times side=\frac{22}{7}\times d$ where $d$ is diameter.

$4\times side=\frac{22}{7}\times 42=132$

$\Rightarrow side=33cm$
