Question

a piece of wire is bent in the shape of equilateral triangle of side 6.6 cm It is re bent in the shape of ring what is the diameter of ring​

Answer 1

the length of wire is 3×6.6

I.e 19.8 because in equilateral triangle all the sides are same

therefore the circle diameter is 19.8

w.k.t π×d is the circumference of circle

π×d = 19.8

d = 19.8/π
