Question from fella, a teacher: 88 litres of oil are poured into a drum 40 cm in diameter. find the depth of the oil in the drum. |
Hi,
The volume of a cylinder is the area of the base, times the height. This is a circular cylinder so the area of the base is π r2 where r is the radius. Thus if the height is h then the volume of the cylinder is
π r2 h cubic units.
One litres is 1000 cubic centimeters so you have a cylindrical shaped tower of oil with a known volume and radius so what is its height?
