Solving the solutions on the cylinder, cone and sphere from the ICSE Solutions For Class 10 Maths will give you clarity on this chapter. In a cylinder, the height h is the perpendicular distance between the bases. It is important to use the perpendicular height (or ‘altitude’) when calculating the volume of an oblique cylinder. The radius r of a cylinder is the radius of a base. If you are given the diameter instead, remember to halve it. An axis is a line joining the center of each base. A cone is a solid that has a circular base and a single vertex. If the vertex is over the center of the base, it is called a right cone. If it is not, it is called an oblique cone. An object that is shaped like a cone is said to be ‘conical’. These questions below belong to the above-mentioned concepts.
