A copper wire of diameter 6mm is evenly wrapped on the cylinder of the lenth 18 cm and diameter 49 cm to cover its whole surface . find the lenth of the wire

the wire covers the top and bottom also?
does the wire iswrapped along the bottom and top of the cylinder
not sure


The lenght of the cylinder is 18cm then No. of turns=18/radius of wire=60 turns Length of wire=No. of turns×lenght of 1 turn where lenght of 1 turn = circumference of cylinder Circumference=154 Length of wire = 154×60=9240
