A 2D sphere is a circle.
A semicircle.
A circle perhaps?
if it a 2D shape it would be a circle,but if it is a 3D shape it would be a sphere
By definition a sphere is 3D. If it were only 2D it would be a circle.
A 2D sphere is a circle.
A sphere.
A semicircle.
A circle perhaps?
it is a 3d shape because it is not flat
The 2D equivalent of a sphere is a circle so it follows that the 2D equivalent of a hemisphere is a semicircle.

By definition a sphere is 3D. If it were only 2D it would be a circle.
There is no 2D shape that makes a sphere, since a sphere is 3D by definition. The closest thing to a 2D sphere is a circle.
A hemisphere is a three dimensional shape that is essentially the same as half of a sphere.
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.
the earth is a sphere but if you look at it as a 2d shape it is a circle
