First, we need to find the volume of the cylinder:
V = πr²h
r = 69/2 = 34.5 cm
V = π(34.5)²h
V = 39507.75h
Next, we need to convert the volume of oil from liters to cubic centimeters:
99 liters = 99000 cubic centimeters
Now we can set up an equation to solve for h:
39507.75h = 99000
h = 99000/39507.75
h = 2.5 cm
Therefore, the oil is 2.5 cm deep in the drum.
V = πr²h
r = 69/2 = 34.5 cm
V = π(34.5)²h
V = 39507.75h
