Question

15. A piece of wire is bent in the shape of a square of each
side 6.6 cm. It is rebent to form a circular ring. What is the e
diameter of the ring?​

Answer 1

Answer:

8.4 cm

Step-by-step explanation:

the perimeter of the square is = 4×6.6=26.4cm

the formula for circumference of the circle :

$2 \times \pi \times r$

since the wire is being rebent the length of the wire will be the same

$2 \times r = d$

there fore the formula of circumference of circle :

$\pi \times d = 26.4 \\ \frac{22}{7} \times d = 26.4 \\ d = \frac{7 \times 26.4}{22} \\ d = 7 \times 1.2 = 8.4cm$
