Question from ab, a student:

the area of the base of the cone shown is 314 cm and it's height is 12 cam what is the volume?


The volume of a circular cone is 1/3 π r2 h where r is the radius and h is the height. The area of the circular base is π r2 where r is the radius. Thus the volume of the cone can be seen as 1/3 (the area of the base) × (the height).
