Question

A copper wire when bent in the form of a square enclosed an area of 272 ¼ cm². If the same wire is bent to form a circle , find its diameter​

Answer 1

Answer:

21

Step-by-step explanation:

Area = 1089/4

Side of the square = 33/2

Perimeter of the square = 4*33/2 = 66

Perimeter of the circle = 2*22/7*r = 66

r = 21/2

Diameter = 2r = 21
