Question

A wire is in the form of a circle of radius $42cm$. It is bent into a square. Find the side of the square. $(Take\pi =\frac{22}{7})$

Answer 1

Length of wire = circumference of circle

$=2\pi r$

$=2\times \frac{22}{7}\times 42=264cm$

Length of wire = Perimeter of square

$264=4a$

So $a=\frac{264}{4}=66cm$

Side of equation $=66cm$
