Question
Find the maximum volume of a cone that can be out of a solid hemisphere of radius
r
.
Open in App
Solution
We have radius of Hemisphere is r.
Radius of
Hemisphere
=
Radius of Cone
and
Radius of
Hemisphere
=
Height of Cone
h = r.....(equation 1)
We know that maximum volume of the cone (V) is = (1/3)
πr²h
i.e,
V
=
