Answer 1

length of wire is 84m
refer to the image for solution

Answer 2

Answer:

Ans=84

Explanation:

Diameter = 1mm

Radius=1/2 mm =   1/20 cm

A wire is a 3D shape name cylinder

So Area of cylinder = 22/7 x r x r x height

66= 22/7 x 1/20 x 1/20 x h

66 x 1400 = 11h

92400= 11h

92400/11 = h

h = 8400 cm

1 m = 100 cm

8400 cm =  84 m

So the answer is 84 meters.
