Lamp oil is sold in cylindrical containers of radius 4cm and height 22cm but only 92% is filled with oil.
1. Find the volume of oil in a container.
Vol = pi*r^2h = pi*4^2*22}} cc for the cylinder
The oil volume = 0.92 times that.
------------------
2. Find the number of lamps that can be filled completely from a container, if each lamp has a capacity of 125ml and no oil is lost in filling the lamps.
# = Vol/125
(rounded down)

3. 24mls are lost every time a lamp is filled. Oil is poured into a lamp until it is full. This procedure is repeated until all the oil in the container is used up. Find the number of lamps that can be filled completely.
# = Vol/(125+24)
(rounded down)
PS 1 ml = 1 milliliter = 1 cc = 1 cubic centimeter
