Answer 1

Answer:

The number of cones needed to empty the container is 12.

Step-by-step-explanation:

We have given the dimensions of a cylindrical container and a cone with hemispherical cap.

For cylindrical container,

Radius ( R ) = 6 cm

Height ( H ) = 15 cm

For cone,

Radius ( r ) = 3 cm

Height ( h ) = 9 cm

Now, we know that,

\displaystyle{\sf\:No.\:of\:cones\:required\:=\:\dfrac{Volume\:of\:cylindrical\:container} {Volume\:of\:ice-cream\:cone}}No.ofconesrequired=

Volumeofice−creamcone
