Most automobiles have a coolant reservoir to catch radiator fluid

Most automobiles have a coolant reservoir to catch radiator fluid that may overflow when the engine is hot. A radiator is made of copper and is filled to its 15.5-L capacity when at 18.0A????1C. What volume of radiator fluid will overflow when the radiator and fluid reach their 95.0A????1C operating temperature, given the fluid's volume coefficient of expansion is

400 ? 10^?6/A????1C

and that of copper is

51 ? 10^?6/A????1C.

Note that most car radiators have operating temperatures of greater than 95.0A????1C.
