Final answer:
The volume of a cylindrical drum can be calculated with the formula V = πr²h, but the radius and height in consistent units are required to perform this calculation, which are not provided in the question.
Step-by-step explanation:
To calculate the volume of a cylindrical drum using the formula V = πr²h, we need the radius (r) and height (h) of the cylinder. Unfortunately, the information provided does not include the dimensions of the drum needed for this calculation.
To proceed with the calculation, we need to know the radius and height of the drum in consistent units (such as centimeters). If the radius is given in meters (as in the example provided with the petroleum ether), it must be converted into centimeters before using the formula. Once we have the correct measurements, we can plug them into the formula to find the volume in cubic centimeters (cm³).
