A semi-circle is a two dimensional figure so it can have area but NOT volume.
To find the area of a semi-circle see the question below.
semicircle is a two-dimensional shape, hence it has an area but does not have a volume.
If the cell has a simple geometric shape, there are formulae that can be used. Otherwise you need to measure the surface area and the volume.
Yes.
It doesn't really matter whether the contents is liquid or otherwise. Formulae for several regular shapes are known - you can use one of them. If you don't find the formula for a specific shape, you can use integration. This is covered in introductory calculus books; roughly speaking, it means dividing the shape into small pieces, for example, small rectangles. That's how many of the well-known formulae are obtained, as well.

None, unless there is a relation between the semicircle and the cone that you have chosen not to share.

There is no single formula for volume. Some simple shapes, such as a cuboid, sphere, cone, pyramid, prism have relatively simple, but different formulae. Other shapes have more complicated formulae.
The volume of a cube is V = x3. The derivative of this is (d/dV)x = 3x2.
2/3*pi*r^2
There are different formulae for different solids such as spheres or polyhedra.
Volume of a pyramid = 1/3*base area*height in cubic units
There are different formulae for different polyhedra and these depend on what information about the polyhedron is given.
You work both out from measurements of the shape and the relevant formulae.
There's no such thing as the "formula for a cube". There are formulae for the surface area, the volume, and the length of the cube's sides, in terms of each other. There are also formulae for the number of edges, the number of vertices, and the number of faces of a cube, in terms of its definition. That's at least six different formulae that come along with a cube. Which quantity are you looking for ?
