Question

derive the formula of volume of frustum of cone

Answer 1

The answer is given below:

Explanation:

• The volume (V) of the frustum of the cone is =1/3 πH (R2 +Rr+r2 ).
• It is gained by cutting the pyramid by a plane parallel.
• The volume of the cone can be found out with the help of its height.
• This is how we will derive the formula and by deriving it we will get this.
• I= $\sqrt{x}$h+(r1+r2)$x^{2}$and 'h' is the height of the frustum.
• TSA of a frustum of a cone = πl(r1 + r2) + πr12 + πr22
• Volume of the frustum of a cone = (1/3) πh (r12 + r22 + r1 r2).
