Answer:
h = 5 cm
Step-by-step explanation:
Given that,
The volume of ice-cream in the cone is half the volume of the cone.
Volume of cone is given by :
r is radius of cone, r = 3 cm
h is height of cone, h = 6 cm
So,
Let is the volume of icecream in the cone. So,
Let H be the depth of the icecream.
Two triangles formed by the cone and the icecream will be similiar. SO,
So, volume of icecream in the cone is :
or
h = 5 cm
So, the depth of the ice-cream is 5 cm.
