Question

A piece of wire when bent in the form of a circle, the radius of the circle becomes
13.3 cm. If the same piece of wire is bent in the form of a rectangle 29.3 cm long,
what will be the width of the rectangle so formed ?​

Answer 1

The length of wire would be same in any shape
So for circle the length would be given by its perimeter =side length of rectangle
Therefore,2pier=2(l+b)
b=pier-l
=3.14*13.3-29.3
=12.46cm
