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."
Semi-circle. (2D) Hemi-sphere (3D)
2D = semi circle 3D = hemisphere
a circle in 3D would acually be called a SPHERE
A sphere
A semi-ellipsoid.
A 3D semi circle
yes it can, i have a uplight that is semi circuluar it is 3d
If its 2d its called a semi-circle, if its 3d its called a semi-sphere.
Semi-circle. (2D) Hemi-sphere (3D)
if it a 2D shape it would be a circle,but if it is a 3D shape it would be a sphere
2D = semi circle 3D = hemisphere
The 3D equivalent of a semicircle is either a hemisphere or a semi-cylinder.
A solid.
A solid
A circle is by definition a 2-dimensional object. It doesn't exist in the third dimension so I suppose you could call a 3d circle an impossibility?It's a hemisphere.
Half a sphere, which is a 3D shape, is called a hemisphere. The semi-circles in the question is a 2D shape and will make a circle.
A semicircle is a two-dimensional (2D) shape. It is a closed curve that divides a circle into two equal parts, with one straight edge and one curved edge. In contrast, three-dimensional (3D) shapes have depth, width, and height, such as cubes, spheres, and pyramids.
