Name: A machinist bores a hole of diameter 1.35 cm in a steel plate at a temperature of 25.0^∘C . What is the cross-sectional area of the bole (a) at 25.0^∘C and (b) when the temperature of the plate is increased to 175^∘C ? Assume that the coefficient of linear expansion remains constant over this temperature range. (Hint: See Exercise 17.26 .
