Question

A piece of wire is bent in the shape of an equilateral triangle each of whose sides measures 8.8cm. This wire is rebent to form a circular ring. What is the diameter of the ring?

Answer 1

Perimeter of triangle=8.8×3=26.4
2πr=26.4
r=4.2
diameter =8.3*cm

thank you
*values are approximate

Answer 2

The perimeter of triangle and circle will be same. Find the circumference and the using 2πr formula, find radius. Multiply radius with 2 and you will get diameter.
