- Frustum of a Cone Formula
- What’s Next?
In the previous segment, we learnt the formulae for surface area and volume of a frustum of a cone. In this segment, we will delve deeper into the concepts.
Some more formulas of the frustum of a cone
Figure 1
In the above figure, O and O’ are the centres of the circular bases.
△ABO is similar to △ACO’ by the AA test of similarity.
Thus,
That is,
This holds true for every cone.
For a frustum with height h and slant height l,
What’s next?
In the next segment of Class 10, we will solve an example on the frustum of a cone.
