Question

A metal wire, when bent in the form of a square of the largest area encloses an area of 484 cm. Find the length of the wire. If the same wire is bent to the largest circle, find: a, Radius of the circle formed b, Area of the circle Circumference of the circle1​

Answer 1

Answer:

Getting the side of the square as √484 cm=22cm,its perimeter =22×4=88cm=2πr (for circle of radius r). So r=88/{2×(22/7)}=7×88/44=14cm.
