How to derive the formula to obtain the volume of the frustum of a cone
This construction video tutorial shows in detail how to obtain the volume of the frustum of a cone.
If we delete the upper portion of a cone, then it will become a cone once again. The lower portion of that cone will become a frustum. Therefore, we can say the part of the cone so acquired as soon as a cone is cut horizontally, is called a frustum of a cone. Frustum is similar to the mold of the slum test.
Learn how the formula is derived for finding out the volume of the frustum.
The frustum of a cone is provided by the variance among the volume of the cone that is cut and the volume of the cone that is obtained.
Volume of frustum of a cone = Volume of the big cone - Volume of small cone.
