Given that

Resistance of wire=26ohm

Diameter of wire=0•3mm=3×10power4

Length of wire=1 m

Now,

Resistivity=resistance×area/length

Area=22/7×radius×radius

=22/7×3×10power4/2

Now,Resistivity=resistance×area/length

=26ohm×22/7×3×10power4×3×10power4/4×1

=1•84×10power6 ohm metre.

So this is the resistivity of manganese

hope this will help you

MrPoizon: 22 x 26 x 9 / 7 x 4 x 10^8

MrPoizon: 5148/28 x 10^8

MrPoizon: 183.85/10^8

MrPoizon: assume it as 184/10^8

MrPoizon: 184/10^2 x 10^6

MrPoizon: 1.84/10^6

MrPoizon: 1.84 x 10^ -6 , 10 and in power -6
