Check out "horizontal cylindric segment" in Wolfram Alpha Online. That is the correct term for the solid you are looking for.
Wolfram Alpha - "The solid cut from a horizontal cylinder of length L and radius R by a single plane oriented parallel to the cylinder's axis of symmetry (i.e., a portion of a horizontal cylindrical tank which is partially filled with fluid) is called a horizontal cylindrical segment."
a circle
a semisphere
a smaller cylinder when cut horizontally. A semi-circle when cut vertically
a hemisphere
half-sphere hemisphere
are you talking about the meniscus? hope thats what you were looking for!
a circle
a semisphere
sphere?
a smaller cylinder when cut horizontally. A semi-circle when cut vertically
If the cylinder is cut in half along the side it is still a cylinder. If the cylinder is cut in half along one of the circular faces it is a horizontal cylindrical segment, which would look like a pig trough not hollowed out.
A cylinder, cone or half of a sphere
a hemisphere
Semi-circle. (2D) Hemi-sphere (3D)
Bisection along a line of symmetry.
How do you get volume in cubic feet from from a height of 5.5 feet in a half circleThe answer depends on whether the shape is a hemisphere or a cylinder cut in half along its axis.
A barrel vault is a structure that spans an open area. It is a ceiling that is like half of a cylinder. Take a soup can and cut it in half from the top to bottom, and then look inside. The shape is that of a barrel vault.
