you have a metal wire of length 1000m and radius of 0.7mm and resistivity is 153.86×10^-6 ohm m. find the resistance of the wire.
please give the answer quickly if you want to become brainliest...


iamthebest1312: You could take π=3.14
akhil1000: ohhh sorry about that

1mm=10^-3m
resistance=resistivity*L/A
A=πr²=(3.14*0.7*0.7×10^-6)m²
resistance=153.86*10^-6*100/3.14*0.49*10^-6
=100000ohm
=100K ohm
please mark as brainliest
