I think you need to use the resistivity formula
R=rho(l/A)
R is resistance, rho is resistivity, l is length and A is diameter
Since you are given length and diameter, you know l and can find A which is the cross-sectional area of the wire. For resistivity, you can search up the resistivity of nichrome
