Area of base of drum (1/2 of diameter of drum in metric units squared * pi) multiplied by height of water in drum in metric units = volume of water in drum in cubic metric units.
So if the drum were 100cm wide, and the water height was 200cm, the volume would be:
(100/2)^2 * pi * 200 = 2500 * pi * 200 = 500000 * pi = 1,570,796 cm^3 (cubic centimeters or cc)

(pi x r2) x depth of water
where r is 1/2 diameter of drum

3.1428 multiplied by r squared and the answer multiplied by the height. All these dimensions in millimeters will give an answer in cubic millimeters.

sounds like u should use volume of a cylinder formula whih is
V = Ïr2h. then u can use any units u want.
