A cylindrical bucket , 32cm high and with radius of base 18cm , is filled with sand. This bucket is emptied on the ground and a conical heap of sand is formed . If the height of the conical heap is 24cm , find the radius and slant height of the heap.

A right circular cylinder has base radius 14 cm and height 21 cm. Find its area of base (or area of each end)

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