What is the resistance of a coil of aluminium wire

The resistance of a coil of aluminium wire at 18?C is 200?.

The temperature of the wire is increased and the resistance rises to 240 ?.

If the temperature coefficient of resistance of aluminium is 0.0039/ ?Cat18?C verify the temperature to which the coil has risen.
