Question

a wire is bent to form a squrebof side 22cm if wire is rebent to form a circle its radius is​

Answer 1

Answer:

Perimeter of square =4s= 4× 22= 88cm

Circumference of circle = 2πr

88. = 2× 22 × r

7

= 88×7 = r

2×22

= 14 cm

Answer 2

Answer:

14 cm

Step-by-step explanation:

Side of Square (a)= 22 cm

So, total length of the wire = 88 cm (22×4)

∵[square has four sides]

From this length wire, we made a circle.

So, this is length is equal to the Perimeter of the circle.

The perimeter of the circle = 2πr = 88

2×(22/7)×r = 88

r = (88×7)÷(2×22)

r = 14 cm

Circle's radius is 14 cm.
