Question

The height of the frustum of a cone is H. Derivate the formula for the
volume of a cone using H, R, and r. Explain each step of solving process.
​

Answer 1

Answer:

The volume of a cone = (1/3) πr2h cubic units

Where,

‘r’ is the base radius of the cone

‘l’ is the slant height of a cone

‘h’ is the height of the cone

As we can see from the above cone formula, the capacity of a cone is one-third of the capacity of the cylinder. That means if we take 1/3rd of the volume of the cylinder, we get the formula for cone volume.
