Find the resistance of copper wire , Physics

The specific resistance of copper is 1.7ohm. find the resistance of copper wire of length 10m and diameter 1mm.

solution) R=ρ*l/A

so ou have ρ,l and r(radius).

you can use the formula now.

but actually unit of specific resistance is not ohm..it is ohm meter.
