A ductile metal wire has resistance R . What will be the resistance of this wire in terms of R if it is stretched to three times its original length, assuming that the density and resistivity of the material do not change when the wire is stretched? ( Hint: The amount of metal does not change, so stretching out the wire will affect its cross-sectional area.)

Resistance depends on the size and shape of a conductor. We expect a long wire to have higher resistance than a short one (everything else being the same) and a thicker wire to have a lower resistance than a thin one. Resistance also depends on the intrinsic property of the conductor called the resistivity. If the resistivity of a particular wire is 70.26x10-8 Ω ⋅ m, the wire is 44.47mm in length, and the radius of the diameter of the wire is 1.95m, what is the resistance of the wire in units of Ohms (Ω)?

Note: It is understood that the unit of your answer is in Ohms (Ω
), however do not explicitly include units in your answer. Enter only a number.
