Question

A wire in a circular shape of raduis 28cm. If it is bent in the form of a square what will be the area of square formed?

Answer 1

Circumference of circle =2pieR 2x22/7x28=176cm .perimeter of square will be 176cm=4xside, side will be 44cm. Area of square is side*side which will be equal to 44*44=1936 cm^2

Answer 2

First we have to find the circumference of the circle= 2$\pi$r
=2 x pi x 28 = 176 sq cm.
Since circumference of the circle=perimeter of square
176= 4a (assuming a is the value of one side)
Therefore a=44 cm.
and area will be $a^{2}$
which is 1936 cm sq.
