Ten identical lengths of wire are laid closely side by side. Their combined width is measured and found to be 14.2 mm. Calculate:

Question

a)the radius of a single wire
b)the volume in mm cubed of a single wire if its length is 10.0 cm. (Volume of a cylinder = π*radius squared*height).

Answer 1

diameter of each is 1.42 mm, so
radius = 0.71 mm

I'm sure you can get the volume now.

Answer 2

1) Ten identical lengths of wire are laid closely side-by-side. Their combined width is measured and found to be 14.2mm. Calculate:
a) the radius of a single wire
b) the volume in mm3 of a single wire if its length is 10.0 cm. (Volume of cylinder = (pie)r^2,where r=radius and h=height

Answer 3

158.43 mm^3

Answer 4

158.43 mm^3

Answer 5

A:::the width is same as diameter so we first divide it by 10 and the by 2 to find the radius because by dividing by 10 you found the width same a diameter and then to find a radius you have to multiply by two
B:::now you have the radius and the length same as height so you use the formula like::(have to convert cm into mm)
(pie)0.71*0.71multiply100=158.33mm^3
