Answer:
154 cm²
Step-by-step explanation:
Given, Area of square formed by bending a steel wire is 121 cm².
∴ Side of square = √121
= 11 cm²
∴ Perimeter of square = 4s
= 44 cm²
So,length of wire = 44 cm².
Given that wire is bent in the form of circle.
∴ Circumference of circle = Length of wire.
2πr = 44
πr = 22
(22/7) * r = 22
22r = 154
r = 7 cm.
Area of the circle:
= πr²
= (22/7) * (7)²
= 154 cm².
Therefore, area of circle = 154 cm².
Hope it helps!
