Not really. Although ellipses are covered in depth in 4 unit, it mainly deals with their properties like the directrices, foci and eccentricity. None of that knowledge is required to answer the question.

This is a perfectly reasonable question for a 2 unit student to be asked. The equation, graph and intercept are all given and the rest is just a standard volumes of revolution question.
