With solution please. I'll give you upvote after.

Five cylindrical wires are made of the same material. Their lengths and radii are

wire 1: length l, radius r wire 2: length V4, radius r/2 wire 3: length V2, radius r/2 wire 4: length l, radius r/2 wire 5: length 51, radius 2r Rank the wires according to their resistances, least to greatest
