The inner diameter of a cylindrical oil barrel is 40cm and its height is 50cm. If the volume of 1l can hold 0.85kg diesel oil, how many kg diesel oil can the barrel hold? Formula

The inner diameter of a cylindrical oil barrel is 40cm and its height is 50cm. If the volume of 1l can hold 0.85kg diesel oil, how many kg diesel oil can the barrel hold? Formula


Radius = 40 / 2 = 20cm = 2DM
50cm=5dm
Volume = 2 * 2 * 3.14 * 5 = 62.8 cubic decimeter (1 cubic decimeter = 1L)
Diesel weight 62.8 * 0.85 = 53.38kg
