A sphere of diameter 3.0cm is mounted into a thin uniform wire of diameter 0.2mm calculate the length of the wire in meters​

Length of the wire in meters​ = 0.000628 meter (Approx.)

Explanation:

Given:

Diameter of wire = 0.2 mm

Find:

Length of the wire in meters​

Computation:

Radius of wire = 0.2 / 2

Radius of wire = 0.1

Length of the wire = Circumference of circle

Circumference of circle = 2πr

Length of the wire = 2πr

Length of the wire = 2(3.14)(0.1)

Length of the wire = 0.628 mm (Approx.)

1 meter = 1,000 mm

So,

Length of the wire in meters​ = 0.000628 meter (Approx.)
