Answer 1

Step-by-step explanation:

Perimeter of triangle=Perimeter of circle

perimeter of triangle=3(6.6)

=19.8cm

Perimeter of circle=2πr

2πr=19.8

πr=9.9

r=9.9*3.14

r=3.15

d=2r

d=2*3.15

d=6.3cm

Q. A piece of wire is bent in the shape of an equilateral triangle of each side 6.6 cm. It is rebent to form a circular ring. What is the diameter of the ring?

Ans. Each side = 6.6 cm

        Perimeter of Equilateral Triangle

        = 3 X SIDE

        = 3 X 6.6

    = 19.8 cm

       

CIRCUMFERENCE = PERIMETER

       Circumference of ring

       = 2 π r ( π means pi )

           OR π d

19.8 = 22 X d

            7

d = 19.8 X 7

          22

d = 0.9 X 7

d = 6.3 cm
