An equilateral triangle shaped wire whose one side is 13 cm Is rebent to form a circular ring. The circumference of ring is
Answers
Answer:
39cm
Step-by-step explanation:
Given, side of the equilateral triangle is 13cm
Therefore,
perimeter of the equilateral triangle = 3×side
=(3×13)cm
=39cm
We know that,
Circumference of the circular ring=Perimeter of the equilateral triangle
Therefore, Circumference of the circular ring=39cm
(since the wire in shape of equilateral triangle is rebent into the shape of the circular ring)
HOPE IT WILL HELP!!
For more information:-
circumference of the circular ring=2πr
39=2×22/7×r
or, r=(39×7/2×22)
or,r=6.20cm or, r=6.2cm
Therefore, Radius of the circular ring is 6.2cm
And Diameter is (6.20×2)cm that is equal to 12.40cm that is equal to 12.4cm
