What is Riemann integration
A drinking glass is a circular cone that is cut with a plane perpendicular to the axis of the cone . The hight of the cone is 10 cm, the diameter of the top is 8 cm and of the bottom is 6 cm. There is a similar drinking glass of the same set, which has twice the volume of the original glass. How many percent the hight of the larger glass is of the original glass' hight?
