Question

A piece of wire is bent in the shape of a equilateral triangle of each side 6.6m. It is Rebent to form a circle. what is the diameter of the circle.

Answer 1

given

side of equilateral triangle = 6.6m

its perimeter = 6.6 × 3 = 19.8m

perimeter of triangle = perimeter of circle

19.8 = 2 pi r

19.8 = 2 × 3.14 × r

2r = diameter

so , diameter = 19.8 / 3.14

diameter = 6.3m
