Download Solution PDFGiven:
A wire in the form of square with side= 11 cm
It is bent to form a circle.
Concept used:
Perimeter of square= 4 × side
Circumference of circle= 2πr
Calculation:
Side of square= 11cm
Perimeter of square= 4 × 11= 44cm
Perimeter of square= Circumference of circle
44= 2πr
⇒ 44= 2 × 22/7 × r
⇒ r = 7cm
∴ Option 4 is the correct answer.
