Question

- A copper wire is bent in the form of a
square of side 44 cm. If it is rebent in
the form of a circle, what will be its
22
radius? Take n =
7​

Answer 1

Step-by-step explanation:

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.Read more on Sarthaks.com - https://www.sarthaks.com/840676/a-wire-is-bent-to-form-a-square-of-side-22-cm-if-the-wire-is-rebent-to-form-a-circle-its-radius-is
