Given:
Radius of the cone = 6
Slant height of the cone = 10
To find:
The lateral area, surface area and volume of the cone.
Solution:
Let h be the height of the cone. By Pythagoras theorem, we get
Taking square root on both sides, we get
The lateral area of a cone is:
The surface area of a cone is:
Volume of cone is:
Therefore, the lateral area of a cone is sq. units, the surface area of a cone is
sq. units and the volume of the cone is
cubic units.
