For a quarter cylinder, A and B must be the same thing. The volume of a quarter cylinder of radius A and height h is 2*pi*A*h. How high is the cylinder?
I have a 24X18 desk and want to buy 2 Quarter Cylinder Aquariums from (Custom Made Acrylic Acrylic Aquarium Water-Tested Quality Control Department Inspected) and Each should be 7-10 gallons. What size should A and B be if I want both aquariums to be next to each other and look like a half cylinder? (And what should the height be)
