The Total solution for NCERT class 6-12
Rachel, anengineering student, was asked to make a model shaped like a cylinder with twocones attached at its two ends by using a thin aluminum sheet.
The diameter of the model is 3 cm and its length is 12 cm. If each cone has a height of 2 cm, find the volume of air contained in the model that Rachel made. (Assume the outer and inner dimensions of the model to be nearly the same.)
