The resistance of a wire of length 250 m is 1 ohm. If the resistivity of the material of wire is 1.6
x 10–8
ohm meter, find the area of cross-section of the wire. How much does the resistance
change if the diameter is doubled?
I cannot understand the part in getting resistance

ok let me check
resistance is 1
resistivity is 1.6 x 10^-8
ya
let me change my answer
wait
solving...
ok
but actually i want to know the second part
