Question

A cone of radius small are cm and height h cm is devided into two parts by drawing a plane through the middle point of its height and parallel to the base what is the ratio of the volume of the original cone to the volume of smaller cone ?​

Answer 1

Answer:

8:1

Explanation:

Volume of cone = (1/3) * π * r² * h

as radius varies linearly with height so at (h/2) radius will be (r/2)

Volume of smaller cone = (1/3) * π * (r/2)² * (h/2)
