Solid geometry is concerned with three-dimensional shapes.
The following diagram shows the formula for the volume of a cone. Scroll down the page for
more examples and solutions on how to use the formula.
A cone is a solid with a circular base. It has a curved surface
which tapers (i.e. decreases in size) to a vertex at the top. The height of the cone is the
perpendicular distance from the base to the vertex.
A right cone is a cone in which the vertex is vertically
above the center of the base. When the vertex of a cone is not vertically above the center of
the base, it is called an oblique cone.
The following diagrams show a right cone and an oblique cone.
In common usage, cones are assumed to be right and circular. Its vertex is vertically above the
center of the base and the base is a circle. However, in general, it could be oblique and its
base can be any shape. This means that technically, a cone is also a pyramid.
Volume Of A Cone
The volume of a right cone is equal to one-third the product of the area of the base and the height.
It is given by the formula:
where r is the radius of the base and h is the perpendicular height of the cone.
Worksheet For Volumes Of Cones.
Example:Calculate the volume of a cone if the height is 12 cm and the radius is 7 cm.
Solution:Volume of the cone
How To Use The Formula To Find The Volume Of A Cone?
This video lesson provides an example of how to determine the volume of a cone.
How To Solve Word Problems Involving Cones?
Example:A Maxicool consists consists of a cone full of ice-cream with a hemisphere of ice-cream on top.
The radius of a hemisphere is 3 cm. The height of the cone is 10 cm. Calculate the total volume
of the ice-cream.
Example:A scoop of strawberry of radius 5 cm is placed in a cone. When the ice-cream melts, it fills two
thirds of the cone. Find the volume of the cone. (Assuming no ice-cream drips outside the cone).
Proof For The Formula Of The Volume Of A Cone
This video will demonstrate that the volume of a cone is on-third that of a cylinder with the
same base and height. This is not a formal proof. You would need to use calculus for a more
