Apiece of gold wire has a diameter of 0.175 cm. how much will precisely 1.00 x 10^5 of the wire weight?

Given data:

Diameter of the gold wire (d) = 0.175 cm

Length of the gold wire (l) = 1.00 * cm

Volume of the given gold wire = volume occupied by a cylindrical object\

                                       = π * *l

here r = radius of the cross section

where : r = d/2

Hence the volume V = π * *l

            =

Density of gold = 19.3 g/cm3

Weight of the gold wire = Density * volume

= *
