Question

 A wire is bent to form a square of side 44cm. If the same wire is rebent into a circle, its radius is.​

Answer 1

Answer:

From the question it is given that, side of square is 22 cm. And also, perimeter of a square and circumference of circle are equal, because the length of the wire is same. Perimeter of square = circumference of circle 4 × side = 2 × π × r 4 × 22 = 2 × (22/7) × r r = (4 × 22 × 7)/(2 × 22) r = 14 cm Therefore, radius of circle is 14 cm
