Question

an equilateral triangle of each side 4.18cm is made of a write. if the same piece of wire is bent in into a ring. find the diameter of the circle ​

Answer 1

side of equilateral triangle=4.18cm

perimeter=3*4.18

=12.54

now

circumference of ring= 2pir

12.54=2*22/7*r

A.T.Q given that same piece of wire bent into a ring that's why we will take perimeter=circumference

12.54*7=44*r

87.78/44=r

r=1.995

diameter =2r

=2*1.995

= 3.99
