Engineering Homework Question?

A circular hole in an aluminum plate is 2.360 cm in diameter at 0.000°CWhat is its diameter (in cm) when the temperature of the plate is raised to 140.7°C? Give your answer to four significant figuresThe linear expansion coefficient of aluminum is 23.00 x 10-6 /C°.Answer unit is in cmThanks in advance

Answer:

Assuming the coefficient is constant with temperature, the new dimeter is: 2.360cm x (1 + (140.7-0.000)degC x 23.00x10^(-6)/degC ) 2.360cm x 1.0032361 2.368 (rounded) ANSWER
foil works, go with that instead.
