Oblique versus Right Cones
An Oblique Cone is one where the vertex is not over the center of its circular base.
An oblique cone is one where the
vertex
is not over the center of the circular base.
In the figure above, drag the vertex point and note how the cone "tilts" to one side when the vertex is not over the base center point.
The opposite is called a 'right cone', where the vertex is above the base center point..
In an oblique cone, the usual method to calculate its surface area no longer works. However the same method for calculating volume works for both right and oblique cones. See Volume of a Cone. You must use the vertical height h of the cone in all cases when calculating the volume.

... I have a small favor to ask. Over the years we have used advertising to support the site so it can remain free for everyone.
However, advertising revenue is falling and I have always hated the ads. So, would you go to Patreon and become a patron of the site?
When we reach the goal I will remove all advertising from the site.
It only takes a minute and any amount would be greatly appreciated.
Thank you for considering it! – John Page
