Question

A piece of wire is in the form of rectangle whose length is 52cm and breadth is 36cm. It is cut at a point and bent in the form of a circle . Find the radius of circle

Answer 1

Perimeter of Rectangle = circumference of the circle.

2(52+36) = 2×π×radius
176= 2×π×radius
88=π×radius

radius=88/π

==> radius= 28.011 cm
