A solid cone of b

Answer :


Let the height of the cone be H m


Radius of the frustum = R = 10 cm


After cutting, the new height of the cone = m


Let the new radius of the cone be r cm


r = = 5 cm [ the cut has been made at the midpoint of the cone]


Volume of the new cone = πr2h


=


Volume of the frustum =


=


=


=
