For a cylinder, the volume equals the area of the base circle multiplied by height.
V=A%5Bc%5Dh
401.92=A%5Bc%5D%282%29
A%5Bc%5D=401.92%2F2=200.96
The area of a circle using its diameter is,
A%5Bc%5D=%28pi%2Ad%5E2%29%2F4
%28pi%2Ad%5E2%29%2F4=200.96
d%5E2=255.87
d=15.996
To the nearest inch, the diameter would be 16 inches.
