Hello, My fuel oil tank is a cylinder 4 feet round by 6 feet. It holds 550 gallons. I would like to be able to measure the depth of the oil in the tank and convert that number to gallons. There are only three depths I am sure of 1) at zero depth there is zero gallons of oil, 2) at 2 feet there are 275 gallons, and 3) at 4 feet depth there are 550 gallons of oil. Today, for example, the oil was 16 inches deep - how many gallons is that? I googled all over the internet and can't seem to find the formula. I would me very grateful for any help. Thank you.
