Question

A wire is bent to form a square of side 22 cm. If the wire is rebent to form a circle,its radius is?​

Answer 1

Answer:

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//

Answer 2

Step-by-step explanation:

Answer

Option (b) is correct.

Given, side of a square is 22cm The wire has same length.

Hence, perimeter of square arid circumference of circle are equal.

ACQ,

Circumference of circle = Perimeter of square

=2×π×r=4×(side)

⇒2×

7

22

×r=4×22

⇒r=

2×22

4×22×7

⇒r=17cm

Therefore, 14cm is the radius of the circle.
