Question

circular piece of thin wire is converted into a square of side 11 cm .Find the radius of the circular wire?​

Answer 1

Answer:

r=3.98cm

Step-by-step explanation:

A circular piece of wire is converted into a square,

∴ The Perimeter of a circle made by wire= Perimeter of the square made by wire

⇒2πr=4a                  (where a is the length of the side of the square)

⇒r=  (4×6.25)/ (2×3.14)

​ ⇒r=3.98cm
