Circle answer

LearningWare 12.1 provides some useful background for this problem. Many hot-water heating systems have a reservoir tank directly to the pipeline, so as to allow for expansion when the water becomes hot. The heating system of a house has 79.7 m of copper pipe whose inside radius is 7.95 x 10’3 m. When the water and pipe are heated from 23.5 to 63.6 °C, what must be the minimum volume of the reservoir tank to hold the overflow of water?
