my course material is unavailable at the moment and I am to figure out this question. I can't remember the formula could someone help me out? A spherical storage tank has a diameter of 48 ft and is full of water. How many delivery trucks with cylindrical tanks measuring 8 ft in diameter and 10 ft long can be completely filled from the storage tank?

I should clarify.. I just need the formula to figure out the volume of the cylindrical tanks please
