Answer 1

Answer:

1:7

Step-by-step explanation:

let the height of the cone be 2h

volume of the cone=1/3 pi r^2 2h

ie 2/3 pi r^2 h

if the cone is divided by a plane parallel to its base passing through the midpoint of its height; then the radius of the smaller cone will be r/2

this can be found out by considering the face of cone as a triangle and applying the similarity criterion

thus the volume of the smaller cone can be found out

the volume of the remaining part can be found out by subtracting this volume by the initial volume of the cone

Answer 2

Here is your answer.

Hope it helps you....

We have to just compare the volumes .

So the volume of frustum is seven times larger than the volume of the cone.
