Question

A circular piece of thin wire is converted into a square of side 6.25 cm. If there is no loss or gain in its
length, find the radius of the circular wire
​

Answer 1

Answer:

3.98 cm or 175/44 cm

Step-by-step explanation:

A circular piece of wire is converted into a square,

∴ circumference of circle made by wire= Perimeter of square made by wire

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

  4a = 4*6.25cm

  4a = 25cm

⇒r=25 * ( 7/44 )

 

⇒r = 3.98cm

0r

175/44 cm
