The area of the circle is radius squared times 3.14. That gives you an area in square feet.
The volume of the tank is that area times depth. That gives you a volume in cubic feet.
Your comment about fish per ft makes no sense at all. Did you mean 2 fish per five square feet? or 2 fish per 5 cubic feet?
Anyway, you have the formulas, I assume you can mulitply and divide it out.
