RD Sharma Solutions Class 9 Chapter 20
RD Sharma Solutions Class 9 Chapter 20 comes with questions and answers related to cone and its dimensions.
Area: In a 2d space, the occupied space by the flat surface is known as area. It is measure in square units.
For 2D figures, areas can be of two types, Total curved surface area and surface area of a right circular cone:
Total surface area: The total area occupied by the surface including the curved part and the base(s).
Curved surface area: The area occupied by the surface excluding the base(s) is known as curved surface area.
Volume: The space occupied by an object, which is measured in cubic units.
A right circular cone is a one having a circular base. Consider a right circular cone having ‘r’ as the base area, ‘h’ as the height of a cone and ‘l’ as a slant height. Then, Total surface area = πr(r+l), Curved surface area = πrl and Volume = 13πr2h
