A hemisphere is a 3-d shape and so does not have a name as a 2-d shape. 2-d sections of a hemisphere can be circles, semicircles, or sections of circles, depending on the inclination of the intersecting plane.
It's a 2D shape.
this is the shape of 2d cone
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.
it a triangle as a 2d shape
The 2D equivalent of a sphere is a circle so it follows that the 2D equivalent of a hemisphere is a semicircle.
A hemisphere is a three dimensional shape that is essentially the same as half of a sphere.
A semi-circle.

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.
it a triangle as a 2d shape
The answer is zero. A 2D shape has no volume.
