Question

A wire is bent to form a square of side 22 cm. if the wire is rebent to form a circle, find its radius.

Answer 1

perimeter of square = 22 x 4 = 88cm

circumference of circle = 2 x 22/7 x r = 88

6.28 x r = 88
r = 88 ÷ 6.28
= 14.01 cm ans

Answer 2

The radius of circle is 14 cm

Step-by-step explanation:

Side of square = 22 cm

Perimeter of square =$4 \times Side = 4 \times 22 = 88 cm$

Perimeter of circle = $2 \pi r = 2 \times \frac{22}{7} \times r$

A wire is bent to form a square of side 22 cm. The wire is rebent to form a circle.

Perimeter of square = Perimeter of circle

$88 = 2 \times \frac{22}{7} \times r$

$\frac{88 \times 7}{2 \times 22}=r$

14 = r

Hence The radius of circle is 14 cm
