maths rules needed for volume problem?

??? The conversion tables are great but the maths rules would be helpful.   I need to work out : I need a round container to take 200 litre water; with a 560mm diameter what should the height be?

An area of a circle with a 560 mm diameter would have a surface area of 246,300.86404143978 square millimeters

We also know 200 liter = 200,000,000 cubic millimeter

200,000,000 cubic millimeter / 246,300.864 square millimeters = 812.015 millimeters

So you need a container 812 millimeters tall
