Question

A wire is bent to form a square with side 77 cm. Same wire rebent to form a circle. Find the radius of the circle​

Answer 1

Answer:

49cm

Step-by-step explanation:

The perimeter of square = length of wire

⇒ length of wire =4× 77=308 cm

Now, a circumference of circle = length of wire

⇒2πr=308cm

r= 308/2π

r = 154/π

r= 154 *7/22. (π=22/7)

r= 7*7

r=49cm
