Question 877434: 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.
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.
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.

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

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
