Question 1033521
What are the shapes at the two ends?  Spheric?
<s>What is the diameter or radius?</s>


You can easily find and use two common formulas once you know the missing information.



Assuming spherical or HEMISPHERIC ends, the two ends together make a whole sphere cut in half.  If the diameter is d, then radius is d/2.


The entire volume capacity would be {{{(4/3)pi*(d/2)^3+2pi*(d/2)(13-2(d/2))}}}; just simplify this and when you know what your diameter is supposed to be, you can then evaluate this expression.


----MY miss; you did say the radius is 3.
