The active element of a certain laser is an ordinary glass rod 19.5 cm long and 1.37 cm in diameter. If the temperature of the rod increases by 75.4°C, calculate its increase in length. (Use 9.0×10-6 °C-1 for the coefficient of linear expansion for glass. Use this value to find the coefficient of volume expansion in the later parts of the problem.)

Calculate its increase in diameter.

Calculate its increase in volume.
