To warm up some milk for a baby, a mother pours milk into a thin-walled glass whose radius is 3.0 cm. The height of the milk in the glass is 5 cm. She then places the glass into a large pan filled with hot water at 66\ deg C. The milk is stirred constantly, so that its temperature is uniform at all times. If the heat transfer coefficient between the water and the glass is 105 W/m 2-\deg C, determine how long it will take in seconds for the milk to warm up from 8\deg C to 35\deg C. Write your answers in 2 decimal figures. Take the properties of the milk to be the same as those of water.
