Sand is pouring from a pipe. The falling sand forms a Cone on the ground in such a way that the height of the Cone is always one-sixth of the radius of the base.
Find `dh/dt` when h=12 cm.

Sand is pouring from a pipe. The falling sand forms a Cone on the ground in such a way that the height of the Cone is always one-sixth of the radius of the base. if the sand is pouring at the rate of 12 cm^3 /s ,Find the rate of change of height of the Cone.

Sand is pouring from a pipe. The falling sand forms a Cone on the ground in such a way that the height of the Cone is always one-sixth of the radius of the base. Establish a relation between the volume 'v' and height 'h' of the Cone using the given condition.

Sand is pouring from a pipe at the rate of 12 cm^3 / s. The falling sand forms a cone on the ground in such a way that the height of the cone is always one-sixth of the radius of the base. How fast if the height of the sand cone increasing when the height is 4 cm ?'

A top is in the shape of a hemisphere of equal radius joined to the base of a cone. The total height of the top is 15 centimetres and the height of the cone is 12 centimetres: Find the volume of the top.

The radius and height of a cone are 12 centimetres, and 6 centimetres respectively. a) What is its volume? b) If this cone is, cut parallel to its base, along the midpoint of its height,what is. the radiús of the small cone obtained? c) What is the volume of the small cone? d) Find the ratio of the volumes of the small cone and the first cone.

A sector of central anigle '45 degree' is cut out from a circle of radius, 12 centimetres, and it is rolled into a cone. What is the radius of the base of this cone and what is its slant height?

The radius and height of wax made cylinder are '6 cm' and '12 cm' respectively. A cone of same base radius and height has been made from this cylinder by cutting out. a) Find the volume of cone. b) How many candles with '1 cm' radius and '12 cm' height can be made using the remaining wax?
